I honeslty think this is too broad of a debate. There are some skill capes, which I even own, that are jokes. Fletching, cooking, and even some may say thieving. But there are others that take up a huge amount of time aka slayer, runecrafting, and farming(mostly waiting time). Even then there are some that a large amount of cash for your average runescape player aka herblore, crafting, prayer, construction, and summoning. To make this an arguement you'd have to set it up with a certain grouping of skill capes instead of just all of them in general.
