im in act 6... stuck in the 2nd freaking battle because the red army keeps bribing the green one and they wreck me togheter

IIRC, the bribing should only take place once you start attacking one of the enemy's castle.

Let your team stay and control the center of the map, and once you farmed enough coins, you can go all-out against the enemy with the most gold first, and your full army should destroy the first castle even after the bribe.

Most important is to make sure your army is usually ahead of the most kills so you can get the most boosts at all times.
