I don't know about you, but lately since starting to do the Arena battles. All the Match Maker and Ladder Ranks up between 19 and 18 seems like one big eternal of a limbo loophole. Tacticsoft really needs to consider making the Match Maker for Arena battles more balanced.
Based on builds, player skill, and finally equal grounds.
Another issue I find is often how the battles start out too close? Or too far away. There needs to be a standard setup so that players don't feel like they are being taken advantage of. Otherwise it's taking about the fun in the game.
