Less and less people are pvp'ing now, sometimes it takes 45-60 mins for a pop to happen.... I've noticed a trend on certain servers you get a few PvP guilds that do nothing but make up 4 man premades and ruin all the fun for people who just want jump into a quick warzone... What happens is you can go against a fully geared out premade who's on vent/mumble/team speak and they pretty much just own everyone...
Bioware you need to add a PUG only warzone option, this will level the playing field more and allow people to just have fun.... If not, less and less people are going to pvp due to frustration with the situation..
I would suggest going to a RP server to PvP, but even there there are premades.
The reason why people choose RP Servers for PvP Guilds/Premades is because they know they'd get owned if they Premaded on a PvP Server, so they go to a RP Server because there aren't as much PvP Guilds there, so it's just easy pickings.
