One unbalanced matchmaking example i just recently encountered:

Bravo team has 3 tier 9s ships and Alpha team has 2 tier 9s ships and 1 tier 11 ship.

Bravo team has 2 APA ships and Alpha team has none.

APA ships doesnt kill ships, Bravo team got outgunned and outpowered by Alpha team...

Addional note: The 2 tier 9s and 1 tier 11 players in Alpha team are in the same fleet, and they are in a platoon party. That's just unfair everytime they go into a platoon battle, they will mostly likely to win.
