Unbalanced Matchmaking in Grand Arena

At a basic level, a game should be fun, and a competitive game mode should be competitive. 

A significant portion of the time, matches are so mismatched that the only real question is whether the opponent plays: If they play, you have almost no chance of winning. If they don't play, you win be default. Both of these scenarios are neither fun nor competitive, and that's a problem. 

There are some possible solutions, such as the Activity Score idea someone mentioned above. But if it doesn't directly make CG money, it's not a priority for them. They're out here making datacrons worse so they can squeeze more money from them, and all while mod management is still awful.
