US Server, WrA, in Gorgrond on the Warlords of Draenor TW (warmode active) shard.
66/66 MS for both world and home.
My spells start out rather fine, with the first 10 or so going off as expected, but from there on out it gets to choppy, 2-3 second waiting times between spells, it seems to calm down after a few minutes of not playing the game, at which point I can cast 10 or so abilities again before getting back to the same issue.
Anyone else having a problem like this? It’s the first time I’ve seen it.
Edit: Upon further investigation of the issue, turning warmode off seemingly fixed the lag as well, though from what I could see with warmode on there was not a single player around Gogrond.
I would like to believe the new Scourge Event has something to do with it, as before Monday I leveled a lock here with warmode on and suffered no lag then, but now monday night is when I began experiencing the lag,
