Can you post replay, where are you doing this?
Whats is your rank in 3v3 and 4v4?
So here is the youtube video from main page that shows NO TD should be used to kill Heaveiest TD.
Alsow shows that any type of skill planes good.
As you can see on the video what I wrote for USF is true. BLocking with mediums and kill it with P47s works exactly the same. THe major advatage of USF is SCOTT that can depoy smoke for FREE without any flare INCREDIBLY FAST and INCREDILBY FAR like no other unit in the game. SO you may hide you approach with very little or just no reaction time for enemy.
