I agree that some of the single target skills can seem very slow (especially the pally ones that have to go on left click), but it can make for a nice change of pace. I also think you'd be suprised by how quick a zealer or well equipped FC bear can kill things (never underestimate things that can one hit KO and attack at 4 frames).Ouch - killing mobs a couple at a time - not fun for me. That is one of the main reasons I don't like playing Zealers/Chargers/Zerkers/Smiters/Conc etc characters!
Long live Mass Destruction.
(Also one of the main reasons I don't like WoW and others like it - killing 1 mob at a time sends me to sleep.)
@Squatman: Would you mind posting what kind of damage you get with that setup? Thanks
