I think there is a major misconception that players who are from 1.0 have level 50 characters, when the truth is that most had only one or two classes at 50, and many more still had none. I'm a returning 1.0 player, but I say that lightly because my highest level character was a level 10 Thaumaturge. The beta forums have mainly  perpetrated the fear and loathing of 1.0 players, and while there are a lot of antagonistic legacy players on the beta forums they are mostly on servers like Hyperion and Excalibur.
Despite Balmung being the 1.0 RP server, it's in no way dominated by 1.0 players. Before Gilgamesh was a thing, Balmung was still the server of choice so many new players jumped on that band wagon and didn't change their mind when options became available, and even after there are still a lot of people who are joining Balmung so the 1.0 players are quickly becoming the minority. As far as RP population goes between the two servers, I can't say for certain but if the number of LS/FC that are on Balmung compared to Gilgamesh is any sign then Balmung has a much larger and diverse population to begin with.
I don't know how bad Gilgamesh will be regarding the different communities joining it, but if it's as bad as people seem to fear I honestly expect we'll see people moving to another server, any of the others available not just Balmung, or we'll see server transfers as soon as they become available post launch. I'm not saying everyone will leave, just that if the trolls and such as as bad as people say they will be, retention rates may be another flaw to consider for Gilgamesh.
