Unlimited Dark Knight

It's not disabled. The one video that I was able to find of the skill the user was in trans while doing it. Even if cooldown starts when the skill stops it wouldn't matter if it fully restores your HP.

Figuring in that both skills (Soul of Chaos and Recovery) are r1, the disarm only drains 10hp/s. Recovery restores 15hp/s. Hopefully it wouldn't last long enough for that extra 5hp/s to overpower Disarm, but if the user has more than 1.2k HP (10hp/s drain would make disarm last 120 seconds, the entire cooldown for Recovery, IF they had or exceeded that amount) then it is highly likely that it could create an infinite trans: The normal skill length, 120+ seconds of disarm, brief period of rest while Recovery does its job, rinse and repeat.

I suppose we'll find out in two days, but still. It's cause for concern. r6 Recovery would be enough to allow for the infinite trans, and each rank after that just shortens the rest period.
