The concepts sound great but look at it this way
the sniper unit:
650hp
50-65 attack
750 range
critical strike ability that does 5x the damage to all targets that are not heroes and are organic
in practice this just pisses off the player, theres no real need for this, it's like crusader v2
the tank unit was just that, a tank unit, I dont recall anything particular about it besides that
the ship was in the works, but it would essentially be a 900hp ship with a weak primary attack and the ability to cast monsoon (i think that's the spell)
I don't remember much more about this
