Pbbbbbbbbbbbbbbbbbbbbbbbbt! 
Fly in the MA..I do...more often than not can't find a fight...in the DA it finds me.
I happen to prefer spending less time getting to a fight, as many do.
There's not really a reason not to...MA folks worried? It wouldn't effect you.
It might actually bring more people over to enjoy some good fights.
If the DA could be coded so that only fights over the lake got ranked as a "fighter" rank, there may be some merit to this as I see it.
But if not, you would get less traffic in the DA, than you already get. No one wants to have their crappy rank from bailing of duelling Krupinski over and over, thrown in their face on 200. The DA is a mano-e-mano place where outcomes are between the parties only. If loss records were kept and published, it would be even harder to get a duel.
The lake is just am small MA furball, with no restriction on perk rides. If you want to keep stats for just that section of the DA, I'm for it, IF they factor ENY into the Rank.
