I am looking for some champion who is good for most of the contents.
Currently in act 6.3.
Note- no Ghost and Moleman
Here is my roster,





I can rank 2 a 6* or r5 a 5*.
Also, I can go for r4 champ if he is good.
I have r4-5 mystic gem(mostly saved for Doom) and class awakening gem of skill and mystic.
Thanks for advice everyone
