i think they're trying to say that the sync doesn't really stand out.

like sly said, there's really nothing exciting about the video, it's kinda boring honestly. do some more with it, like screenpumps, shake the screen during a hit or slow down enough after a hit to make it actually look appealing instead of going down from 5000% speed to 4000%, it doesn't really stand out and that's why people are saying there's no sync

anyway the angles were nice but i wasn't really impressed by the video, it was kinda boring
