I'm sorry but just because you arn't good with a certain unit doesn't mean they're not good. I can beat most people with Teemo, and I can usually push a lane by myself as Teemo, against 2 or 3 people, and do fine. I can do fine as Gangplank as well.
I play every champion, I have more wins than losses on all but Kassadin. I can beat most people with Teemo as well and of course it is easy to push a lane with your poison, just load it up any time a champion tries to get near since his range is good. He's just useless in a teamfight for the most part.
You'll be disappointed.
I know Shaco is banned. I'm saving for Malzahar - Prophet of the Void.
Any1 here just do TT? I only do 3v3 cause 5v5s sucl
3v3 require more teamwork n map control.
And I disagree with AP bein better then AD on ezreal.
His q and E all he needs. Sure his ult does damage. but it also gives 5 stacks on his passive (which means he already has more attack speed to spam Q)
Teemo - He's just not good. You can play him in super situational teams, but, 99.99% of the time, not worth it. He has a blind that shuts down melee dps. Combine with exhaust. he can shut down Tyrn/jax/xin/ect...
Evelynn - Melee stealth, 400g on an oracle and you won't win. She just bad. I agree
Twitch - Stealth but super squishy, any sort of CC and you die. If I play twitch. its always cleanse + flash. Always attack after every1 else to not be focused. poistion urself to escape so u can flash + go invis
Gangplank - If you farm all game, avoid teamfights, get loads of items, you will be average endgame. He's just terrible after some nerfs.
I have a 20% chance to crit page JUST for him. Crit pistol is awesome. He has a spell that removes alll on him. and his ult slows. (and uits global)
Ryze - He's great if you are starting out, but the range on his spells are awful and as you get better he's easier to beat, any sort of magic resistance and he is useless. Good ryze do their job and hit the main dps. then just go support. magic resist sacrifice to do no damage? you are doing your job.
Twisted Fate - Super squishy and hard to master, requires some luck also. He king of killing towers on 5v5s. He can stun and if going with attack speed he can do damage
Good champions, learn to play them if they are fun for you:
Shaco - Jumps through walls, has a slow, great backdoor potential and awesome map control. BANNED. no skill. When I play shaco I always have decieve ready. all you gotta do if you are gonna die.
Heimerdinger - Best pusher in the game right now, a good Heimer is unbeatable. WW ult on him b4 he can freeze tower + teammates. Dead. sry but he easy to kill.
Vladimir - He is so OP right now, you can get tons of health and tons of damage and be unkillable lategame even after a bad start. No skill. king of being a [kitty]. He has a "get out of jail free card". His ult is OP and LIES when you try to cleanse it out.
Taric - A stun, a heal, great pusher, great lane partner early game for any champion. He can kill towers easy, but lacks dps unless with a good team. Same with soraka. She just a mana+heal [bleep]. only as good your team.
Soraka - 2 Heals, a mana restoration spell, silence, and a formidable pusher.
Morgana - She is very powerful at the moment, needs nerfing. 2 stuns, a spell shield and the best short cooldown AoE in game.
Remember, I'm talking about high ELO where you can depend on your team and everyone has good map awareness, teamfights and ganking are done in the blink of an eye, you don't lose because of bad players on your team but because you get simply outplayed or the other team has a better setup which you didn't realise whilst picking champions, however the latter doesn't really happen much.
I didn't say AP Ezrael is better than AD. I said it is better at lategame. Early game, AD Ezrael is much better and you can harass so easily, you push towers fast because of your attack speed and should dominate whichever lane you are in. However, lategame when teamfights are the most reliant thing, AP is far better because if you can catch the entire enemy team with your ult that's such a huge advantage.
Teemo - As I said, situational, you can blind, but that's not a great form of CC, you might aswell go Ashe/Ezrael and kite the melee. Xin can still knockup through a blind, Trynd can still spin and slow you through a blind, Jax can still stun you through a blind. And you can always take an exhaust. You get good map awareness with him, because of mushrooms but you have a low base AD rating, so endgame, someone like Ashe/Ez/Yi will be much more powerful, even with a blind they will still kill you if they are of equal skill. There are just better carries.
Twitch - I kind of didn't go into detail for a reason but, you can play twitch but he's really not that great at a higher ELO because of team positioning, you won't just get into a lane and everyone spam their spells, you'll be fighting over dragon, Baron, different buffs and in the jungle. You need to go everywhere as stealth, but even with Flash and cleanse you will die fast because teams will walk together and never alone. Twitch relies heavily on positioning, but one exhaust WILL shut him down. This is a time Teemo IS good, because you can lay down mushrooms and see where twitch is at all times, but in the end people will just pay the extra 60g to get vision wards instead of sight wards.
Gangplank - I know someone who has 300 games with Gangplank alone, he used to be good but now he says, just don't play him because he is bad, which he is. He has a built in cleanse which is good, but it doesn't help when you die in 3 hits anyway. You rely heavily on getting a full critpage that you can't get survivability items, and you die fast, even without a stun. His ultimate isn't good either, since you stack crit and AD and the ult scales with AP, it's just an annoyance and prevents tower pushing, it's just random. You cannot win a high ELO game with a Gangplank on your team, fact.
Ryze - You say that the enemy getting magic resist to counter Ryze instead of damage items is better because it means you do your job? Defensive items are standard in high ELO. Ryze is just a bad character but can be played at Low ELO because of his potential to nuke and is not so reliant on runes.
Twisted Fate - He is best played AP, so I'm just not going to go into detail about this because you obviously have no idea about this champion. Again, you CAN play him but it's not recommend, again very team reliant.
Shaco - If you don't use deceive except for getting away then you don't know how to play Shaco. It's not good doing almost nothing then just deceiving away. He is very easy to play, but he is very hard to play WELL. A good Shaco will crush and pound you and backdoor when your team is trying to push. I have 20+ wins and 3 or less losses on 3v3 as him. I don't like to play him 5v5 since I don't build him great, but a good Shaco is unstoppable, always banned, agreed.
Heimerdinger - Obviously you haven't played versus any good Heimers. A good Heimer will push minions and NOT a tower to get minion kills and feed off these rather than champion kills whilst at the same time denying the other mid. I play Heimer with 8.5 magic pen, 14 mana regen and 300 health runes, I am unkillable at start game and don't push a tower tactically. I force the other player to go back with harass, push half a tower at once whilst taking a trip to another lane and getting 2 kills. A lot of Heimers level their turrets first, which isn't bad, but you can play him differently. I farm for a Zhonya's ring ASAP for teamfights, it works.
