How far are you in Twisting Corridors?

Tried first floor alone. Finished last boss after second try. Understood that with my class and power it gives me I will never finish it soon™
Searched for the grps and finished this whole run in a two days with lazy running. Some classes are disbalanced although I thought that my rogue with Kyrian combo points which refreshing itself and deals damage as 20 combo points finisher is imbalanced as hell. Warlocks and Shadow priests easily can outdamage anyone. But again sometimes anima powers are just garbage and you rely on your other people. So I recommend to go with grp only no matter which iLvl they have it doesn’t really matter.
