In the end, none of them mean anything. No matter what skill one does, it's the same idea. Herblore and fletcching are the exact same skill, Fishing and woodcutting are the same, attack, defense, mage, range, hp, strength, and slayer are all the same exact skill. In the end, it doesn't take "skill" to get one of these, it just takes time. I doubt any of you people actually "play" the game, you just let the game run while you're on youtube, or these forums, or just watching TV. Hell, the quest cape is the only one respectable, at least you have to pay attention to get that.
