Blizzard pretty much proved that most twinks are more interested in pwning noobs than fighting other twinks. When they made PvP give experience, and gave the twinks an option to lock their xp, and that would cause them to go to their own twink-only BGs to fight other locked-xp people, the twinks swore up and down that they only wanted to fight those other twinks. However, when it was implemented, it was a ghost queue. Very few came to them...because they couldn't pwn noobs anymore.
So, I don't believe twinks when they say that crap anymore. If they were telling the truth, those queues would have been full of twinks wanting to kill each other. But they weren't, and the twinks are not interested in an equal fight.
Back to Rift, I really hope they keep the Lock XP feature, as I like to use it to keep myself from overleveling the storyline when questing, especially when I get a bunch of xp from a dungeon or a flurry of zone invasions. Maybe make 'Lock XP' not work in PvP?
