This game exists since 10 years, over 10 years, we've been through many starts, servers were overcrowded as hell at the beginning, I'm surprised how stupid you're or naive if you believe that dex has any chances.
Files? Doesn't matter these days, days "we wanna retail like" are gone cuz having H5 off files is nothing special and shows, proves that it really doesn't matter if zergs from russia for example which spend most time on retail or privs with off files are playing now on servers runned by java, because online is high. Online is a point, noone cares if you've got uber 101 % retail files if server is empty, damn... I can't believe that simple things need to be told.
Anyway it's not even Dex fail, just everything has beginning and the end, excluding russians.
Online at start is the most important and most encouraging thing for others people to decide them to join or not. It's like first baby's breath, faster, better.
