Complaining here will do nothing. They are not in charge of Class changes or anything of the sort. The Class changes are built around Korea's content/current patches. Telling NCwest to stop boosting a class or constantly complaining about Destroyers isnt going to help anything. At all. I get where people are coming from, but we're getting these class changes way before we're getting the gear/content other regions have.
Just one of those instances where you have to suck it up honestly. That or take a break for a while and come back later.
