Yea, I know a friend, Pinball, did really well with totem necro up to Tier 13 labyrinth I believe? But it took a lot of gear to get to that point. I have not played it.
Totem necro is very fun and easy play. However it drops off HARD after 125+ IMO. Like Crash said you will need a lot of gear to handle ubers after 125. The double TP with bend the shadows and the TP charm makes the class very mobile but squishy.
However I do not like this seasons changes to totems.
