So about cheats at top level?

[kayll]

I've seen some wildly questionable timing on ability use, but I never equate it to cheating. I'm sure there are script users out there, but I don't think its that prevalent. I have however seen my fair share of speed hackers and teleporters and I even managed to catch one back in season 2 while streaming, but again, I don't think cheating is super prevalent as a whole, though I imagine in the top 100 there are some shenanigans.

Do you have a video with better resolution?
To me it looks like you used a gap closer on a BLM as soon as they used Aetherial Manipulation on you twice, further hinted at by them using two ice casts on you without a cast bar ever showing up for them on the enemy party menu.
If I remember correctly 2 players using gap closers on each other leads to some wonky stuff happening and the other looking like they are teleporting.
Here is an example.
