I thought that Chanvaala will be new OP hero this patch but it's not so consistent, on the other hand Tess, while everyone forcing elementals, is very very good. Once elementals will be nerfed and start to rotate it's over I guess, but now it's really worthy to try her.
I had so many good runs with Tess, now I never skip her.
Yeh - Tess is the beneficiary of a very OP chase minion that is an auto buy. I bet she also would have been nuts if she was around when Amalgam was. I wonder if the fix to Djinn will knock her down a bit.
