Any suggestions will be appreciated

Arena is not a good indicator of how good a team is. The equalizing effect of it is nothing like the rest of the game. Just sayin

Ur correct that we generally dont fight equal opponents and most of the teams are unbalanced (with one character having much more power ) , but arena helps me make effiecient lineups which can defeat higher power opponents , its basically a tester . Any lineup that performs good in arena is generally good outside of it too. Thnx for yur suggestion btw , i will try to get some sage worlds out on that lineup

Arena lineup and norm play lineup are totally different gameplay components for me, different settings and effectiveness require different approach. Two gameplay in one game, that's fun for me, it would be boring if i had only one formation for best performance all the time.
