I play on www.neverendless-wow.com

The server has over 1K players online all the time, sometimes up to 2.5K online during the day

It's mostly pvp server though.. not a lot of raids
private servers fail imo.
yeah i use to play neverendless server too its really gd :D but the thing is its on newest patch lots of downloads and i have limited
i used to play on naxpgaming but idk why my account was deleted(or the server was shutdown) btw its a very nice,addictive game :)
tried playing on officials ? you'll see addiction then :P
