Perhaps limiting unit type based on unit points per stage would help?

Example, first round of the event you have X points. Next round you gain points. I noticed there was an element of ranking in regards to match ups in the last event. My first few matches were not too bad, but as soon as I gained about 130 or so points it was just phalanx/PT or similar combos.

Something should dynamically allow match ups with similarly outfitted players in addition to limiting their unit usage.
