Necro Summoner looks OP? I am playing him right now, 110 lvl (with some totems) and i am going through hell difficulty without any issues. Act 4 right now, still no challenge at all. My army is killing everything so fast, i have to spam only night hawks. I have finished Infernal Machine in about 30 seconds without even getting any damage and few other ubers without a single death.
It is supposed to be that easy? The game will get harder later? I didnt play Median much, but for me Necro Summoner looks like a total OP build.
