Outside from the whole balance issue there is 2 things that I would really like to see in PvP. I don't know if there is another opinion forum like this since I couldn't find one but here it is.
1) The PvP que should be across all the servers, I think that would make a quicker que time, and you won't have to be paired with the same people from your server that has proven they don't know how to play for the next 3 hours.
2) I think it would be nice if you could choose your WZ. Now I only think this would work if the que was through all the servers, but the reason I want this is simple. I hate hutt ball, I'm no good at hutt ball, and I have no plan to get better at it.; which in unfair to the people who love it and are good at it. Why should my lack of skills and passion keep someone else who is pro at it from winning because I'm the handicap.
This is just my opinion but I think that it would work better in the long run for elder game PvP.
