I think that if played well, a necro can be a force to be reckoned with in PvM. I dont agree with people who say, "Summon necs suck late game. They cant kill anything, etc" I have beat the game with my summon nec and found little difficulty even in late game areas.
The reason that people think summon necros suck is because they dont know how to raise effectively. I use lvl 18 Bone Horrors, and Bone Fiends, I dont use Bone Minion because they dont do enough to be worth 25 energy IMO.
Anyway, I guess my point is...
Thats why I dont think summon necs suck. Its not that many, but I wanted a screenshot where they weren't all clumped together, its hard to see them when they are. And they are in a nice even circle in this one. Its only like 19-20 which is about what I average in the crystal desert.
So, thats basically why I think summon necros are good. I will always go to bat for summon necros on these forums, I feel we are sometimes under-rated.
