You've seen the video from the live letter showing what they had worked on for a jump animation so far right? What did you think of that? Yoshi himself said the height was a little extreme. I agree with him there, but I was actually really impressed with the motions of the characters especially the landing. It was also impressive to see the jumping while running was well done. I know that was merely an early stage test, but it still looked good to me, albeit a little high.

I've always been very impressed with all of the motions in the game so far, I've yet to see an emote or an attack that I can say is unrealistic or impossible. For me it's one of FFXIV's greatest accomplishments in the game so far.
