Out of the different Final Fantasy 11 private servers, I like Valhalla the most.
Valhalla has TRUSTs, 90 level cap, XP gain rate same as retail. Movement speed is increased, all Home Point crystal warps and outpost warps are unlocked. They have some nice extra content like a unique gear augment system, a few custom dungeons, Dynamis D raids are unlocked. Rise of the Zilart, Treasures of AU, Wings of the Goddess expansions are all unlocked and working properly.
So anyway if you are tried of the slow grind to 75 on the other private servers like Horizon or Eden, then come check out Valhalla.
