The sniper isn't really a counter unit. They're just better at a longer range, yet good players can non-scope kill up close. They're vulnerable to pretty much everything. I see where you're coming from, though.
Aye... The Dark Trooper is utterly appalling. No real steering involved. That's supposed to be an improvement from Jet Trooper... I think an improvement would be more fuel and greater speed. Not a quick boost quarter way across the map (usually into a bottomless pit of some sort).
