You should look that up on a QUEST section --> but since your not first of all you should of had max your pts and defended your keep for I think 30 mins as well as taken a keep after enemy had it 45 mins and heard the taking of the keep. OK you should get a medal if you didn't you never capped or didn't do the other two requirements.
Check internet this is discusion is posted as a QUEST or on MYTHIC might be the only damn thing they post.
