i think it'd be great if we could get new duel arena's with the new worlds being added in and that they've been the same areas for 10 years it would be a great refresh to a aging arena.
now for the second part the pvp systems needs a overhaul i shouldn't be able to get put against a level 40 when im only lvl 14 no matter how high my rank is its very unfair and not my problem that people aren't as good that you have to be paired up against someone double your level.
