Sudden Lag Spikes post 2.1 patch

So before the patch I never experienced any kind of lag. Maybe during passing through congested areas such as Mor Dhona or Quarrymill at peak times I would slow down or experience a bit of frame rate drop. But ever since the patch I have been experiencing lag so bad that my screen is showing during battle the skill I casted before. For example I casted Full Thrust > Leg sweep. Full thrust would only show once I casted already Leg sweep sometimes a bit after that even.

Right now I'm hoping its due to "optimization" with the recent re splitting of the data center things. Or even because there's a huge uptick on players back (Although I am doubtful on this considering even on dungeons I'm lagging at the start)

If this is due to the resplitting of the data centers and it is permanent then I'm permanently screwed by SE as well.

I hope to at least get some light into this whether other players are experiencing this too and hopefully, just hopefully an official response from a mod.
