Thats the thing though, none of the servers are currently west coast. The reason why they are unpopulated is because they all cater towards the same player base.
A west coast server pretty much all west coast players would play on. While it would lessen the population of the 2 Central/East servers a bit, the population would still be decent on the West Coast server because ALL of the players on the West coast server (except for clan specific like ATS and Hospitaller) would play on them.
In Washington, during peak hours I consistently get 100+ ping on the current NA servers. This is with a very stable FIOS 25/5 connection.
Like mentioned, the difference between 60-80 isnt great, but the difference between 30 and 100+ is huge. It's still playable, but I would certainly donate towards a West coast server to drop it down to 30.
On a side note: I have good friends that work in gaming server farms (WA based Netriver specifically), and would personally pay for a server. However, I know only people with clout are allowed to have a cRPG server (such as Gorath). This is why I'm so interested in financing, I would do it if someone that knows how and is allowed to do it would set it up. As long as its in the range of WA-CA without going any further east than Utah...
