I have been playing this game from the beginning. Why. WHY are you pairing non GL rosters with GL rosters in GAC. It is impossible! I'm raging and proud of it because I'm right. Come at me you cowards...
I don't see anyone say "no it's perfect". I just read a lot of posts saying the matchmaking is what it is and you have the control over what chars you want to develop. So if you want to be more successful in GAC start improving your roster accordingly - and that means getting meta chars and GL's and not relic 7 a Stormtrooper Han or zeta a Farmboy Luke.
