Stealth Tank missiles could use a tweak so they don't go into the ground when aiming at a unit with some elevation between the two of you. They lock on to the middle of the tank and force you, a pretty weak tank, to get really close to the enemy. Dumb missiles don't really work since they just fly straight.
I found out that the MSA Hud glitch can be negated if you go in first person, apparently it only affects you in third person.
