I have a small 12 man FC Promathia's Chains (PROC) that might suit you. We have 1 group on SCoB and would like to start a 2nd group once we add more members.
We do Primals/ST/BCoB/exp on our non-SCoB nights so we always have something to do.
Some of us do some PVP as well. We are not a RP FC but we do have a few people in the FC who do RP. We just achieved rank 8 and plan to buy a house asap (2.4)
We use Ventrillo but we don't force anyone to talk. We have a couple member who are just like you and prefer to listen.

If this sounds like it might be a good fit for you look me up in game!
