Again, I use the TCS in a dogfight before the merge or when I've gained angles such that I'm chasing. It allows me to see what the opponent is doing and make a judgement call. If you think this is useless that's fine, I respect your opinion, and I will agree to disagree with you.
THIS!
ps the only way my tcs locks anything (with jester) is if i get a radar lock, is that what you meant?
