I stepped into PvP a few weeks ago after a long long long (PvP-)break and currently play in a 'decent' 2k RBG team with my Resto-Druid. I have a few friends that are interested in PvP, however, most of them already have the Battlemaster-Achievement or are not aiming for achievements at all. I'm sitting at ~19.4k right now with 12x/27x PvP achievements done and would love to get some medium/hard ones.
My question: are there communities out there organizing cross-realm achievement groups for PvP? What is the best way to get those achievements, if you do not have 5++ friends eager to help you?
