SOME HEALTHY SUGGESTIONS FROM VETERAN..(kabam do thank me later)
1).Remove the option of selling any champion-why is this option available any way?and after people sell their champs they are less likely to return back.
2).New backgrounds for in game fight should be available for purchase from units.(which can also be seen by attacker in war fight).
3). 1 vs 1 arena should be replaced with live 1 on 1 duel with your friends in real time(although too much to ask but will bring life to game).
