I assume there's not many so wont be picky otherwise, will check out any progression server. Heavy preference for it to be pre-3rd jobs, if they're going to add them in thats fine.
You can try Havoc SAGA @ https://havocsaga.com the server is new, I'm the servers owner and the server offers 25x/25x/15x rate currently the server population is not that great we have 10-20 active players playing on different timezone but the overall online players are 40-50 with Autotrade.
I plan on having the server progress till the 4th job update but first I want to see players progress in the game so equipments won't be a problem when new update release.
The server also has some custom modification like Crimson Weapons are already available in the current Episode: Hugel, and cash points can be earned by joining automated events also hunt them inside the designated dungeon of the day.
