duels wouldn't be a great addition to this game. Not because it wouldn't add anything or "insert XXX reason about how bad and toxic wild PvP is", but because of job balance.

"But don't bring that here it has no importance"

It has. A lot. some classes are just too cheated in 1v1 situations (namely, scholar) to allow any form of 1v1 to come. This game has been created with a team approach, which means the classes are totally unbalanced when it comes to solo playing (SCH or SMN > all) but as a group, the balance is nearly perfect. It would result in only 2 things :

A) people stop 1v1 totally. No one ever uses this feature because it's either "you're in the right job" or "you're wrecked" so they just stop thinking about it

B) the community becomes insanely toxic with people ganking people who just want to play their way through the game, insults, bashing, shaming, etc... Things that happen in all the other MMOs I know with wild PvP.

I'm not sure if you want that for the game, but I'm sure I don't. B is out of the question. As for A... well, Wolf's den is already a unused feature because people don't like it. I'd rather SE fix this before trying to add an other unused feature
