If HTC wanted the TT V bases left alone they would have a red border around them making them un-capturable, but since they don't anything goes.....as it should be.
Why should TT be any different from any other place on the map? If you want a good fight then defend those bases. If all you want to do is spawn camp in TT then by all meens do it, but don't complain when your base gets captured because you were too busy racking up spawn kills instead of protecting your base.
There has been a ton of threads about this subject. People ruining the fun for everyone else. Call the Whaaaabulance. Taking those bases IS fun for some people. You have an opertunity to stop it if you choose.
I say leave TT as it is. If it aint broke, don't try to fix it.
