I do if I can use them
tank destroyers in front of prism
terrorist flack bombs for early rush
demo trucks if you are on a map where you can hide them and drive into a base
tesla tanks for infantry spam (ie dogs)
mikoz issue is he bails when he gets pts and uses 100 nicks, not his dogs. he's half the reason xwis died, people like him rip ect....always more concerned with their 50 pt lead.
but its obvious that those units are extremely flawed in both ra2 and yr.
play a game on MX and you'll notice that those specialty units are much for viable once they are adjusted.
