A lot of hc stuff was double before 6.0 . there summon necro and drood were really powerfull. Because of nerfs like explosion corps and hell cows i dont know... I played 3 days and ripped m'y maniac necro....
I think New mecanism Will force ppl to play in team to go late game.
Anyway Last patch i did titch lichking, a3 boss that loot the shrunken head unique charm, a5 Red portal, and 2 3 inferno cows...once again Red portal xp nerf and cow lvl Will make this more difficult, but ill be glad to test things again as soon as i re lvl my necro :-D
