Im pretty good with most other terran units. The only one i have trouble with is the Battlecruiser. I find it way less effects than most other terran units. For one thing its too slow to do any kind of harrass with and i find it to not be very effective if the enemy has any kind of anti air at all. I mean it would be alright if you could get it out really early but by the time you do your opponent will easily have something to defend against a few. Sure they are ok for support if you have other units mixed in with them but, even then they dont even seem worth all the money it cost for them. Tell me how you guys use them in matches.
