If we consider the current version. Cold based build are a little bit OP - I know that other really good. But we need to agree that Spellbreaker with Soulrend build were over others.
In the Ashes of Malmouth will allow more several OP builds that stand out from the rest or will be 1 or 2 that will be over the rest??
I know that some people could not agree about the current top build. But, I played a lot of multiplayer and the guys with Soulrend were much better than the rest (in general).
And if you think that have the MOST OP build, share with me.
This is in the same kind of street, ppl showing of their theory crafting skills:
