Ever since the last patch I have been having issues. Primarily in dungeons, raids, and main cities.
There will be issues where other players will freeze in place for a few seconds, and then suddenly lurch forward. Boss attacks will come out in odd intervals instead of the steady pace they usually do (I.e. Amphibious Talos in Malikah's Well dungeon. When he uses Swift Spill his attacks came out relatively normal paced, but then stopped for a second, and then rapid fired the rest of his rotation).

I have pinged the server I'm on (Coeurl - Crystal), and have been getting an average of 3 packet losses per 20 pings. Resetting my router has fixed the issue for a few minutes, but starting an Alliance Raid almost always brings the stuttering issue back.

Playing classes with time sensitive abilities (Black Mage's Umbral Ice/Fire), or properly drawing aggro from my allies as a Tank has become almost impossible with the sudden lag spikes I've been receiving, and was wondering if it is a known issue that has appeared recently, and if anyone knows a fix.
