But it is possible to make sth like: "don't attack in case another one attacks"?

My problem with 3 different buttons would be, that I only have a limited amount of keys on my keyboard. I'm currently playing a warlock and a druid (single), but I've got barely enough keys ^^;

using: qwe asd to move
Fastbuttons: yxcvghrtz123456 CAPS
Slower buttons: Alt+ --> qweasdyxc123

But... Since I probably won't be using ground targetting spells I got some keys free... Ok, at least the single ones should work.

thanks
