Hey Novon. Mouth Trumpet Cavalry is a mature C5 WH group that is accepting new members. Mainly US TZ with a healthy dash of EU. I can tell you after over 9 years in Eve, in which I have been a part of most of the relevant group, that MCAV is one of the top tier groups in Eve. We function a little differently, but it works wonders. WH space is the place to be for PvP and PvE in Eve.
Take a look at our post: C5 MCAV is Recruiting all Skill levels or join “mcav-public” in game.
