So, I had no idea this was tooken into place, but your pet will not attack a player in the same faction as you are, I understand why that would have been tooken into place, Siege reasons etc! However, what's a tamer to do when he's being attacked by someone in the same faction? The pet(s) won't counterattack in your defense, even if it is guarding you! You should at least be able to defend yourself then, because the aggressor was the one going for you! I think that it should be fixed to where at least it'll defend for you, or since pvp taming templates are going to be nerfed again in the next publish, to get rid of it altogether, or be able to defend you at the very least!
