ARENA CHANGES!!! Give it a chance.
I personally love the new system. The AI is aggressive enough to deal with higher pi matches. Its not a boring match after equal match. The best improvement in years. I can grab a team of r1 5*s and start playing with no worries of facing a 51k pi team. I hate that it is being changed back so soon because people cant adapt to a new system and pattern. BTW any noob could start playing arenas now and have good success if they have any skill at all. Great Job KABAM!!!!!
