I’m somewhere in the middle. I like having access to clickies for boost (and would just get bored if all I was doing was swapping a weapon set out) but there’s a limit…
Specifically I’m thinking of Monks. Playing my 20 Shintao can really be a pita if I’m looking for optimized play. Between Light strikes, Stunning Fist, Improved Sunder, Triple Earth, Triple Water and lower levels of Fire and Air it’s an overload. Especially if the game doesn’t read one of the buttons clicked…Bam! Total suckage, I just missed my Anti Stun, or SP discount.
My Intim-12/6/2 Fighter/Pally/Monk on the other hand has just the right amount. I occasionally have to juggle a little but to keep up with his actives, but they all (easily) fit on two hot bars. I can focus more on enjoying the content than fighting to keep up the optimal combinations of abilities.
Finally, I really don’t think casters fall into the same category. I rarely find myself smashing through spells the same way I do other classes active abilities. I think a previous poster nailed it when they said the only real clicky I associate with caster are DoT’s (maybe Clerics aura/burst….But not as much as DoT’s)
