It doesn't matter how significant the issues with Balmung are, in part because their extent is unknowable and unquantifiable. I think the situation here is very simple: every server has a culture and the culture will not necessarily fit well with every individual RPer.
The benefit of having multiple server communities is that there are more cultures for players to explore in order to find one that fits them.
