Remove 3rd spec from BG

[Gman]

As in title. BG is allready unbalanced (Skill wise) Why add more points of discussion.

3rd spec isn't more powerfull than whats already out there. People just aren't used to it yet. It's already bad that the devs were so toxic as to hand out rewards for shackled isles at the same time they block out 3rd spec.

People just aren't used to fighting 3rd spec; stop whining and learn to pvp. Boy people wheren't even this toxic about warden's blade ward & resilience
