The drones in the matchplay arena often offer a better fight than what you can find the MA.
While the dueling arena might not be the same as the old days being able to pick your fighting area and opponent, most of the time there is nobody else in the que, and at least your opponent is predictable.
Have had a lot of fun in the 3 vs 3 and 4 vs 4 options a few years back.
It would be cool if somehow the two versions of the DA could be combined to get the best of both worlds.
But let's be honest.. the majority of whats left here isn't looking for a fight. They are looking to bomb sheds and hide in trees, the least resistance the better.
At the end of the day you can still duel in there, it just appears nobody ever does.
