Actually in west there are the same gold farmers, speed hackers and dupers that there are in East.EAST also know as: Turkish world and the others with too many players legals and illegals. 55% (especially turks are koxp, dupe etc.. where u can found on every single server from k.o). and it's true k.o work with turkish this game is played more often for those guys. some of them are funny some of the just koxp dupe and are too freaking in those games.
WEST also know as empty server (u're right) with right know with 200 - 230 players 60+ . just one lvl 70 from the ally as far that I know. this server looks like when the K.O Started, but without turkish.. It's the First server that started with other ppl that not speak turkish that's why is a little bit empty. looks like a very popular private server, and without too many koxp.
In my opinnion it's ok this desicion about east and west cuz west (american ppl and more) it's looking as ARES (with most turkish ppl), so could be great if k.o get too many players from sudamerica, northamerica and europe ^^.
if u love turkish and too many players online go east, and if u love the best private server with not too many koxp go west (it's not empty but they have less players than east)
