Are the devs aware of the very frustrating server-wide lag that happens several times during the day for a few minutes each? It's ruining raids, dungeons, pvp, you name it. The general enjoyment of playing on the realm is suffering a whole lot, all thanks to the lag.
There are a lot of variables here. Like where you from, your ISP and the route they used to connect you to the server, the amount of players, etc.
The devs put a lot of effort to give us a good experience, but if you live in Chile (like me), your MS going to be 170+, not to mention the lag pikes time to time.
