I play on Drak'Tharon or something like that, also on Blood Hoof, I play both Horde and alliance! I mainly PvP..

The last server I played on was Nordrassil-EU, though that's an EU realm. Decent population.

Tbh, look on WoWProgress to get an idea of server sizes.

I was on Dragonmaw-US or as it was nicknamed Lagonmaw.

wow freakz

When im able to play I play on Ysondre-US. I got a Horde toon named Vochanka.

i was on Sargeras

I used to be on Moon Guard. Worst mistake I made... the memories of the ERP still haunt me. I quit after LK because my guild disbanded and I had very little reason to continue playing.
