Yeah im pretty uneasy with going into ubers with my DH too... Especially since i havent done them in SC!
Im really afraid of EHP requirements, I have 170k dps unbuffed but only 53 k hp and 500@ res... What do you think?
i think raka will eat you in one hit if youre not careful. sk can be pretty confusing too with maghda. her locust in combination with random arcane spots and skeletton spawns is not to be underestimated. id first try it with a less squishy class f.e. barb/monk so you get a general idea of how to run them.
