Enough, we want a client-side user interface!

[Reika]

tl;dr version:

Client Side = Actions are registered immediately and only need a server confirmation for certain aspects, e.g searching or lists display immediately if the server isn't struggling.

Server Side = Actions requires a confirmation from the server as well as an answer. Multiply this by the thousands of others needing said responses. It also produces pretty hefty latency problems and why the stamina and cooldown timers are out of whack.

And is one causes for the server stability problemim sure. probably the major cause.
