i'll assume glory since you didn't say one and i doubt you are using fury - so 16 prayer bonus at 70 prayer you will use 19.5 (4) dose prayer potions an hour using piety with that setup. to decrease this number, get a cape with a prayer bonus (soulwars, fire, ardougne) or get a fury instead of a glory.
because jagex removed RWT from the list of reportable options This sounds to me like an entirely different discussion. I could be mistaken, but it seems to me unlikely that this is the reason which would motivate calling the OP a "rat". Jagex removed the option because they DON'T WANT PEOPLE REPORTING for this because there's no way to know that someone is RWTing in game. OP goes out of her way to report players for this despite Jagex's desires otherwise. if going out of your way to be a rat doesn't make you a rat, i don't know what is.
It's unfortunate that you can't report people for scamming when they aren't scamming? He means that it's unfortunate that you can't report someone for intending to scam. It's always better to catch someone before they take a victim but Jagex doesn't see it that way. yes, much better to collaterally ban and mute all the legitimate hosters of these games
Who slays for the drops anymore? The free trade/wildy change tanked most of the drops. Now it's only done for fun :P i slay for slayer xp, charms, and effigies and jungle/desert wyrms and sp mages are terrible at all 3 of those
personally i block tasks that are a combination of slow experience, bad drops, bad charms, and bad effigies but it's all up to personal preference - if you really hate those tasks, leave them blocked
i would keep doing them - you need all the charms you can get at that level, and they should be quite easy with your stats - 80 melees, 70 prayer for piety, and 68 summoning for bunyip - you should have no trouble ps: your perm list is full of all really good tasks (cept hellhounds, which are just okay)
you can still profit a little bit without banking all the ashes - they drop death runes, high level herb seeds, rune boots and helmets. but black demons are a great option as well because they have excellent crimson and effigy rates. if you have the agility level for the spiked blades jump (80 agil, can be done at 75 w/ summer pie) you can bank ashes very quickly with duel rings and taverly house tabs. while you are "gone banking", you can leave your cannon firing so that you get ranged xp and charms/ashes/effigies while you are banking.
:s well slayer can sometimes be a nice surprise i shoulda brought some summoning potions, i left a lot of ashes :( o also i passed 23m slayer xp today too
fire cape > ardougne at mithril dragons. 4 str for 5 attack is definitely a good trade. only task i would say sw cape is best is dagannoths if i were at DKS. IM 23M SLAYER XP THEREFORE I AM RIGHT
