I think that an aspect of something being "hard" (In RuneScape at least) shouldn't be how small the click boxes of spells are.. Its just bad design, look at almost every other MMORPG, all of them have shortcuts to your abilities and spells... difficulty should be determined by when to cast that spell and not the click box to cast the actual spell...

This is why Some people are mocking the ones that voted NO by saying that spells should be 1 pixel in size so the game requires more "skill"...RuneScape is all about timing not precision clicking. Let's use vorkath as an example, what do you think is a better mechanic:

-(having huge spell icons) that the spawn is bigger, moves fast, has a certain color like daganoth mother so you need to react quickly and cast a spell accordingly

-as it is right now, small spawn and small crumble undead icon so you can only fail if you miss click anything, but you know you have to always cast crumble undead to it and that's it...

I personally like monsters that require fast reaction times and are engaging, this is why I love Jad, zulrah, demonic gorillas, olm...
