Were the MPE Green Potions ever fixed?

I've heard some people say they have, and some say they're still broken.

They were fixed, unless Nexon recently messed them up again.

Worked fine when I used one last night.

Apparently they were "super" fixed, allowing classes to go beyond their speed caps when using the green potion by allowing every other attack speed increasing skill/whatnot to work when it normally wouldn't.

While i don't think speed cap should exist at all i feel this is really broken because there's only 1 class that never hits speed cap but can, while every other class either does naturally or does extremely easily.
