Why no dueling?

But it needs to go when actual PvP grows or the community will continue to die out, since PvP focused players aren't going to flock to casual content.

iLevel caps don't make content casual. They mean when you win, the loser can't go "We'll your gear was better". What makes PvP casual is the complete lack of any form of long term scoring/leaderboards/tournaments outside that worthless thing on the Lodestone and what players can try to hobble together themselves with the mess that is Wolves' Den. Reason #1 why "We have new Frontlines planned and a Frontlines Roulette for you in 2.5!" doesn't instill much faith in me... They really should be working on Wolves' Den right now, but I guess Frontlines is more popular...

Still, being on equal grounds gear-wise doesn't make something casual. It makes matches fair.
