Well here`s a site that might help You
InfiniteAion is around 80% working aion server , it got SOOO MANY features but is low-rate server 1x exp and 1x drop
westaion is on top only bcoz it got some vote rewards :S and has not many features working
Naxpgamind doesnt even work , its wow private server , dont click
I suggest You to Join Aion Atomix REAL SERVER HIGH RATE! its 15 on toplist but its bcoz members are not voting for it , it got nice community like 50ppl++ online i think , its good as for beta server , it got many features with Boost Dmg , got class change i think its best of the sv`s , i actually play in there.
As i said that`s my last post prob in this year i wish You all have fun
MERRY CHRISTMAS!!
