I would love for them to put in a 1v1 arena. Yes people say "Just duel" but it's more than just a duel for me and a lot of other people out there. They could put it in just for fun but add a ranking system, add small rewards for winning.
Yeah, people say "then we would be facing tanks and healers" the way talents are right now they could easily implement a system where only certain specs can join. DPS specialization only. People say "It wouldn't be balanced, class X will always beat class Y". That is definitely not true, skill always matters in the end.
Is there anyone else that would like to see this? Comment your thoughts on why or why not.
