Yep I'll just write to Korea so they can make a 4.6 version only for euroaion with that crap taken out. Smart.
Now for real. "Why should they fix it?"
Because it's gamebreaking? Once you know the good premade coop teams or you know their skins you can just dodge them indefinitely and give them a DEFAULT LOSS because there is a bug in the game which occurs when the enemy team leaves before the arena starts, which results in ticket loss and default loss for both teams.
Basically if everyone starts doing this, the "best" coop teams will never play, because they will get dodged every single time.
I am not implying I'm a part of one of the best coop teams, but I imagine it is frustrating to max out your gear, get a great team together and get dodged every single time.
Did I really have to explain all of this?
