The laws of the universe mean nothing.
Agreed, we need time to gather conclusions before we start calling certain characters overpowered.The only easy mode character that I fought is Killer Frost. The vortex, as Killer Frost players mistakenly call it, is just a simple-minded 50/50 mix ups.
But I hope NRS has learned from their mistakes. Even with a scrubby character like Frost, no one wants anything toned down until the game develops.
