I could be completely off, so don't quote me. But I'm guessing that a lot of the PvP related issues that I'm seeing have to do with population. What I mean to say it, they're probably waiting till the population increases enough to incorperate more of the PvP things that we're used to seeing such as; Selectable WZ's, Bracketed WZ's, etc.
Right now, with the population (while good and growing) not being high enough, it would be really bad if they bracketed the PvP AND had selectable WZ's. This would mean that there would be entire brackets or WZ's that never popped because there just wouldn't be enough people playing in them.
I'd guess that as population increases, they'll add these in and we'll start seeing a richer PvP experience. Just hang in there.
Again, that's all just my guessing, hopefully I'm right.
Cheers!
