So its been easier getting my assault to level up since i hit 18. Way better with all my tanking skills lol. Now I have a new challenge for myself, get a 3 star combat rating on all my characters. So far I have 3 1/2 on my assault, 3 on my robo, 2 on my medic, and 2 on my recon. Its so hard trying to play good with my recon. Wish me luck!
