Until you do something to address the toxicity of 9pcs Total Guard, it almost doesn't matter what skills new champions have unless they have a triple hit AoE, and none of the new toons have that, so you can keep 'em. 

....except, of course, for the new Mythical, who can hit 4 times AoE....and will further break the game.  

I have been a staunch defender of Raid amongst my clanmates that are itching for Godforge, but you know what, they may be right.  The time may have come to kick this game to the curb.
