1. bola shot - the AoE can be exploited to break CC. If you trap the healer and use bola shot on the dps, he has 1 sec to move in 5y range of the healer to break him free. Or he can just stay on top of the healer and you can't use your focus dump.
2. snipe - you lose cobra/steady, can't move while casting, no way to use this in PVP ever
3. lone wolf - you lose too much utility by having no pet - cc, freedom, crit immunity, chasing rogues, healers
so it seems that if you want to PVP as MM or Survival, you can't take any of the 3 top level talents for pvp, because all of them make you worse.
I think they must change something - hopefully remove snipe altogether or make bola not affect CCed targets
