The bottom line for any game is enjoyment. These updates have affect every area of the game play and I now find the game a joke and not so enjoyable anymore. I spent a few months getting into the top 500 ranks and building characters to combat higher players.
Now I'm lucky enough to complete tier 1 challenge and get pass three Galatica war missions. I would recommend talking to people like marvel alliance on how they overcame similar problems in their game.
A major change like this should have been beta tested by users and these flaws in the game would have been quickly identified. Get your characters right and I dont want to see 6,000 critical do nothing to my enemies, it's a joke.
