Well i'll tell you what. Even IF 2B is not broken, the stuff from her is very different than other characters. That coupled with how i've heard that she is very easy to pick up and use means she is going to demand a lot of knowledge to properly defend against and counter her moveset.... for anyone that purchases her and even has access to the lab. Anyone else, my condolences. You have your work cut out for you.
Cause you know... its one thing to tell a player complaining about a character, to "go to the lab", "learn the matchup", or "get good, scrub".
But ummm, that is a little bit different when it requires an additional purchase to even do that, for a character they may or may not even like.
