I feel like part of the issue is low population for PvP,
Part of it is that PvP actions just mangle your job to the point that it's got basically nothing to do with what you've been doing in PvE,
another part is that there's only one mode where you're gonna be matched up with people who are anywhere near your skill level, so 9 times out of 10, unless you're queuing for the Feast, you're going to just get roflstomped.
