Anybody Else Having Trouble Transitioning?

I've pretty much played URF nonstop since it's return. Not even thinking about touching Normal Draft or Ranked so long as URF remained a playable mode.

And I would like to take a moment to thank Riot for bringing it back in the first place. I never got the chance to play it initially. And as frustrating as it has been in certain games (Hello Shaco, Sona, Morgana), I am going to miss URF.

But now, I have a horrible feeling about returning to the regular game modes of LoL. I've been in URF mode for the past two weeks and I will feel completely lost not understanding why my abilities are taking so much longer now to be cast again, how I am not able to just #yolo turrets in 7 seconds, how enemy champions are able to have this thing called "sustain" and why I can't just teleport to whatever lane is having trouble within 30 seconds anymore.

Anybody else gonna feel like a war torn soldier returning from the fields of justice not sure how to cope with a much more relaxed way of life?
