Disagreeing with the new kishin egg rewards. I don't think it takes away from the difficulty at all. It would be impossible for almost anyone to come even close with the old system. Especially since finding a partner to stick with reliably for years is nothing short of a miracle. You still have to climb your way up and participate in a lot of missions, it's just actually something more people can accomplish now.

So really it's more or less taking a game mechanic that'll probably never get used into something that comes into play.
