Last I heard, Gilgamesh doesn't even have much RP going on. Most of them paid transferred to Balmung. Or went elsewhere. But a poster on the previous page has the right idea. It's not just Balmung. Part of the issue is on the entire datacenter. Two of the most populated servers (at least during expansions and patches) are together. It would be wiser to separate Balmung and Gilgamesh into different datacenters and then work on balancing out their populations, in my opinion. This isn't a case of "buy better servers." It doesn't work that way.
