I don't have this problem with my other chars.
I am trying a hammerdin, and not succeeding well so far. That is, at Cllvl 21 I am still mostly using melee, since I kill much faster with charge/zeal than with hammers. HOWEVER, I am trying.
One of the things setting me back is hotkey troubles.
With my other chars, it's not problem. But a paladin's aura can ONLY go on the right mouse button side. So that means if I want to cast hammers with Conc on (and I want that), then hammers have to go on the left mouse button. But doing that causes me to run around like a fool, not casting hammers, until I remember to hold down the "shift" key, which annoys me greatly (especially since I play on a laptop). There is no toggle to always stand still.
Is there a way around this? Any tips?
