Serbule proper should be an instance of its own so you can do the quests outside without having to deal with the lag of the afkers in the town. Think how Everquest did their areas.

That's sounds much like Guildwars. That really ruined GW for me as it felt like it made the "mmo" feeling of the world and the towns just into a hub based / lobby based game imo

That's a huge amount of work for a fix we may not need in a few days, and causes other problems.

GW wasn't/isn't an open world MMO, it was specifically designed to be 'hub based'. The player base will spread out. The fix is patience :)

As soon as population went down in Serb, lag left. It will be back today, but we can see that the fix is people spreading more to other zones as they level.
