Green Potions Working as Intended?

Okay someone has some explaining to do.

This video is KMS Demon Slayer.

That is clearly breaking speed cap. IDK if that's the green potion or something else she is using, but that is just too fast for it to be at a capped speed.

EDIT:
Okay that's weird. It felt like the first minute of the minute she was attacking fast, but the second minute of the vid she is attacking at capped speed. IDK what to make of this.

The potion works exactly as it should in KMS (in other words, not breaking cap), already tested this on my wind breaker months ago, even after the revamp it works as intended. But like I said before, you never know with Nexon. They can say one thing is intended because they like it and then another minute they can say it doesnt work as intended at all. If you really would want a clearification just go by KMS, things CAN be eventually fixed (hello good old GMS LHC) but it will take time for Nexon america to decide if its a priority to fix/remove/keep whatever.
