NA player from the UK here -- I've noticed this issue about 2 to 3 days ago during a Frontline match which is now unplayable due to action delays. Even switching gear set has a second or two delay, it's ridiculous. I mean, I can play on my EU alt where everything runs fine in the meantime but I'd rather play on my main.

So yeah, I hope this issue will be resolved very soon because playing on NA right now is no good (unless I want to do nothing but AFK) and that makes me sad.
