We are working on the exchange issue and will be fixing it very soon, as well as the PVP dropdown box.
People who leave the fleet will remain on the leaderboard. We may revisit this in the future.
Can you give some more information about fleet events and falling out of the map? Are you part of a large fleet? That may help in determining the problem.
are you saying the pvp button could go back on the hud? and out of the drop down(of shame)? that would be awesome! there is that dilithium store button in your inventory now, under the refine button so its not needed on the hud anymore imo.
I;d rather have the leaderboard remain as is. Those folks did contribute and if you;re using some sort of payment system like some fleets are, removing those players would make it hard for them to receive credit.
Maybe a mark of some sort would be a better idea?....
