that would make no sense, becouse balance means, that every character in every stage should have mostly the same chances to win.
It will durn some time for us ppl, to know all diffrent tactics characters have.
For example, you can spam sniping with radec in long range, or you can play mid range with him, using graps as melee.
Sometimes, you just think characters are op, becouse, you never played them, and dont know their weaknesses in a certain way.
Try to play with the nightmares you cant beat, to understand them better.
1 or 2 months, we will be able to tell whos op or not, but not in this beta for sure.
