If you are seriously struggling in PvP, let me burst your bubble now and say you will not magically start owning in PvP just because Thorn and TLW are getting nerfed. After the "Re balance" you will still get owned in PvP. This patch will mostly impact players who are already doing well in PvP but want to try different weapons and still be competitive. If you are horrible, the patch ain't going to make you an amazing PvP player overnight.
Edit: I Don't care what your k/d is or if you are good or not. My point is that the weapon patch will not take someone who is consistently at the bottom of the score board to the top over night. It will not make a team who struggle to get few wins to flawless in ToO over night.

If anything they will do worse. Anything that lengthens TTK increases the skill gap so the good players will do better and the bad players will get worse.
