Kill speed is pretty fast, though as with Barb you'll probably run past mobs in Chaos Church (no Tele in there...). You can encounter some nasty Elites or Super Uniques with Physical and Ele resists all at once in which case you just run past them; A great therapy for some of us OCD users that have to kill and collect everything.

I killed all mobs in Chaos church every time i went there. Well i like clean areas so i killed mobs probably everywhere i could, because xp, drops and safety. There is really no immunes when you stack some auras and use procs. Eq vise this mod has a lot of options to take down enemies with random immunities. Plus medium charms give boost to rainbow damage and -enemy res. As for merc i like act 5 with sazaby set -> freezing aura when full set and a lot of fire/cold/light add ons. Plus he atacks super fast and is tanky enough.
In the end all regular mobs died from 1-2 throws, uber mobs died in 4-8 hits. You should build in a way that you see every hit taking damage from monster hp. If fight takes more than 10-15s with a mob, you doing it wrong. Because boss with same immunity will take forever and it's not worth to waste time.
