Now I don't pvp, however people are saying that expertise is terrible for us in pvp. Apparently getting behind your enemy negates their chance to parry or dodge your attacks, and as hunters, that's near impossible to do. Why? Because the only way to do so effectively at range would be to attack them while they are attacking someone else. Any other time, they just have to keep turning to face you. And we stand ~40 yards away from the enemy, unlike melee who can easily run through the enemy, turn around, and attack their behinds in less than 5 yards. Also, I believe that all our defensive abilities are affected by silence. Traps, aspects, and deterrence. I could be wrong about that last one though. But if we are disarmed, there is no way for us to attack other than with our pet, who, let's face it, doesn't do much damage at all. At best it can buy you a second or two to get away via entrapments.
