Agreed. Last patches seem to prove UAT is almost useless. It looks like they want to check the server won't crash, then they push live without giving players any chance to submit feedback.
Most of the time TKs with it are accidents due to its speed and someone hopping out badly. The other day we had a guy going out of his way to TK on purpose. I removed him from the game for that.
I tend to run over other brothers because they see my big tank and expect that the tank will stop in 0 seconds flat
