.. First off, Since the lag issue doesn't seem to be going away ANYTIME SOON.
Having lag because you're near someone with a slower connection seems Brilliant mind you.
When I join a battle and the other guy takes 5 minutes to load up, while the rest of us load up, and he's the one who suffers the least it seems wrong..
So the simple Change?
Make it so that even if you lose in a PLAYER VRS PLAYER match, that you still get equipments.
Since, y'know, the lag seems staged to avoid you playing with other players.
