I never usually bother with the PTS and just wait for final patches to hit the main game. I had no idea that arenas were going to be forced upon people. I don't mind the occasional one, or ranked games, but don't want them to be the main part of my SWTOR PvP experience.
I hate to be that guy (and I know this doesn't effect BioWare or anyone else), but I have literally just unsubbed for the first time since the game came out. I never thought I'd be saying that.
In my personal opinion, the arena queuing system should have been totally separate from regular warzones.
