I am pretty sure you can do the same with Ranger, Rogue and Warrior setup if you abuse skills like Walk in Shadows and Back stab religiously. My rogue can fell a high priority targets in one round or severely damage it most of the time, activate Fast Track, Walk in Shadows and do the same again. More often than not that is two targets down in 1-3 rounds. Mages cannot do this usually since their spells cost a lot of AP while a 100% crit dagger attack costs 2 AP.
Oh and to people who complain about melee skills and ranged attacks being able to miss, those attacks can crit and benefit from Bully. Spells cannot either.
