Since it is well within the powers of the warpportal team to move maps around to different servers, i propose that we have a weekly poll for renewal players to vote for which map that they would be focusing the majority of their woe time on.
After each week, the map with the highest votes could be moved to a server on its own, or a server that has very minimal load. I believe this could help with the lag issue without needing kRO intervention.
