You guys might wanna check out what is happening in Stormwind, Goldrinn realm.
Super ultra lag, everything has like a 5-10 second delay, mounting up, changing items on the bag, on the character, using abilities etc. Latency values show normal both home and world.
I noticed this happening for the 3rd time now, only happens in Stormwind. It’s happening right now, 02 july 2019 03:28pm local time, 11:28am PDT.
