They haven't said yet. Hopefully they'll come back but there's no way of knowing right now.
I switched from using a 3D2Y Powerhouse team to using TS Luffy, Sabo, Koala, INTvankov, and Swimsuit Boa. Still kinda slow because Sabo's countdown is so high and I don't have hardly any sockets on anybody besides Luffy and Ivankov but this is really easy. So far, I'm 4/7 on Doffy's skills; while I'd like it be lower, nineteen turns is already fine for pretty much any team I'd use him on.
