@Jayyyygs Thanks for that. But my blue demon Meliodas is already doing good as AoE unit for farming and Death Matches. Also, I can't farm anymore. I ran out of everything: dungeon keys, gold keys, etc. And I can't buy them using coins or real money.
I want to improve my PvP. I was doing good when PvP was 4v4, winning against opponent with same CC as me. Now it's 3v3 again, I'm doing pretty terribly (using the first 4 above, Meliodas as sub).
