You have to face the fact that the server isn't getting seeded properly. We are also not against diversity. In fact we probably have the most diverse set of servers out of any other community. Not only do we have vanilla servers, we also have Saxton, Deathrun, Jailbreak, Idle, and Trade servers. If we were lazy about it, we could've easily just hosted 2fort, dustbowl, and turbine. But when a server falls below our standards, we change it.
Most donators are probably just content to get on their main server for 3-4 hours a day during prime time and never worry about seeding issues, which we worry about all the time. Due to the update and the way Valve controls traffic through quickplay, we cannot control the fact that there are tens of thousands of people being funneled into invasion maps.
If moving to LA is suitable for you, then by all means do it. If the invasion fad dies out, your home server will be added to the history of thousands of new players. Turning a 24/7 server into a rotation server is not something we would like to do and is bad for the population as well.
