So I found this post in another thread:

How should I interpret this relatively to the issue at hand in this thread? Does it mean the "300ms check" isn't confirmed as an actual issue? It certainly isn't a "bug", since it's technically a design choice; but with the lack of response from SE, I'm now not even sure they're considering this issue as game-breaking, nor even as a serious one.

Really, some kind of clarification on this "design choice" would be appreciated. If it's built in your online engine SE, and there's just no way you can change that, please tell us — so that those of us who value a fast and responsive online experience can move to another MMORPG who has a chance of providing such a service.

People will get tired of waiting, and your lack of honesty on this topic isn't helping their staying anyway. At least be frank and blunt about this issue, so that players can make a choice for themselves based on honest information about this game's design, and likely (or unlikely) future improvements regarding the network implementation.
