Either it’s FPS or input lag this game has stupid amounts of it and needs to be addressed. Stop the expansions stop the crown items fix the damn lag already.
I was just thinking about that. Often when I first log in the lag is absolutely awful, most noticeable with significant delays to movement and that awful juddering you get when turning to face another direction. Logging out and back in often "fixes" it (by which I assume you just get a less laggy server) but it's an excruciatingly slow process and as it's a bit of a dice-roll you may just get the same thing again.
