Why I'm matched against upper divisions in GAC?

Wth? I thought I was supposed to fight against my own division only.

Nope. Divisions dictate rewards and number of squads to deploy. Leagues can limit matchmaking.

If your roster is top-heavy - a lot of GP concentrated in the top {x} toons - you may find yourself matched with rosters 1 or 2 Divisions above you.
