In other RTS games (both Starcrafts are a good example), each faction has a stealth threat, i.e. a unit capable of dealing terrible damage to the opponent if they don't have detection. In our case, detection is changed to radar. When you have a radar covering the entire non-Cybran enemy, you don't get a lot of surprises from them, which is lame. Can these factions get stealth units please? Maybe the T2 raiding tanks? Discuss.
P. S. Don't throw your balance discussion guideline in my face, I am not proposing anything in particular.
