I'm going to post this here as a possible vent thread. Sometimes, the instagibs are horrendous. I ran into a Champ pack that had Horde and Arcane Enchanted, MALACHORS. Of course this is on Nightmare, Act 3. Freaking 40k Life on the minions, that would 2 or 3 shot me.
12k Hp with with 2.5k armor, and 1.5k DPS. Which is slaughter with most of Hell Minions. Though I gave up on this pack and has to simply quit after dying roughly 10+ times. QQ man, QQ.
