Y'all are forgetting that certain units only do a percentage of damage vs. Certain types of units. Like Probe Droids do 400% damage to certain types of units. Mobile Heavy Cannons are great against vehicles. Security Droids & their Sonic Grenade & Tognath Marksmen with their special shot (espcially @ level 5 & above Tognath). At-Dp only does 75% damage to some types of units, but make an interesting combo with MHC & Repair Droids. Snipers are hard to kill if on a wall or under a shield & do a ton of DPS. Bikes have 80 speed after level 7 & huge defensive perks (Not as good as Probe Droids, but much better health & speed). Look @ your Striker class units & use those for defense. The striker class is made for defense.
