Main rotations are Whis and Beerus, and INT UI Goku and the USS duo.
Floaters are gonna be the LR Beerus and Whis,Champa and SSB Vegeta
Given he awakens from the event, I think it's not a stretch to say that he will probably be tailor made to beat it.
Now here comes the question, what buffs can they give him to make it so that even F2P players can beat frontier easily.
Just imagine the potential of a Buu saga Dokkan Frontier.
Like fighting fat Buu with an ultra boosted AGL SSJ3 Angel Goku.
Or like TEQ Vegito basically gaining immortality and like 500% percent attack against Buuhan.
Or INT MV and PHY MV gaining buffs against the Angel Goku fight.
Like a Mbs Frontier would be so fun.
