I just remember at the end of Beta, Theatrics were starting to dominate.
Momma said knock you out....is all i'm saying.

But for really realz, the Beta test showed us that each and every type dominated at different points. There is a definite ebb and flow to the game which makes it exciting. There is no auto pilot to victory mode, the astute and diligent manager will be the most successful, regardless of which kind of gladiator(s) they are running.
