Some Things To Think About
First off, the Tag Team Arena Tournament. Is it fair to have a tournament where in that area there is a limit to the amount of players in the tiers? You may have an insane team but if everyone else does too you could be stuck in the very low tiers leading to be unable to compete except from gems via $. If this is added and Tag Team is not changed, then please do not introduce these in fusions because this would completely prohibit many players from completeing the fusion.
Next, I love the preset idea and all, but only 10 teams for PVE? That's barely enough for dungeons, not counting any other PVE aspect in the game.
Lastly, the AI introduction thing is great. But there is one area that it will Not help in- the Fire Knight. AI in Fire Knight needs to be fixed once and for all. Abilities with Buffs, Increase Turn Meter, and Revives first, and then the ability with the most hits, otherwise the A1, or something like that. Alternatively, each champions AI needs to be specifically fixed.
