I've been seeing negative and positive reviews on their page recently. I think they're just bashing each other, please take a look.
I even saw 1 one response from ImperialRO accusing the reviewer as GM of ForsakenRO /hmm Sounds very childish.
Not sure what's going on between them, but don't worry about it. It is in the review guidelines that mentioning other server name(s) in a negative way is not allowed. Those reviews will get removed when we get to them.
