Why did you even make a poll about Ch/Eu races? There are already many 'only ch' server and the one missing right now is a 90 cap ch-eu. Thats why we all came on your thread and we were already ready to join it after seeing the features, including of course the " CH-EU" and not CH only.
It's simple, if you don't like EU you can just join another ch only server that will die in 2 weeks. As most of ppl said, if you worry about skills balance you can just add 10% extra phy/mag attck and 10% extra phy/mag def on chinese characters that should be enough.
Once again, this poll has nothing to do here since you already made your server ch and eu and not only ch, imo you'll lose a lot of players if you change it to chinese.
