Shadow Protector (Shadow Arts III):
When you stealth an ally, they gain regeneration for 5 seconds.
This is partially broken. If I do not have regeneration on myself and I use a stealth skill, then it will apply regeneration as expected. However, if I stealth myself again before the regeneration runs out, it will not apply regeneration again. If I have half a second of regeneration left when I go into stealth, regeneration will still expire in half a second.
I’ve tested this using Cloak and Dagger, Blinding Powder, Shadow Trap, and Shadow Refuge in various orders. I cannot get the regeneration to apply to myself if I already have regeneration. This is pretty damaging to my build. I’ve tested this mostly on golems in the mists, although I see the same things on players while in a match.
I haven’t tested how this works with regeneration given by other players yet, or how it works when applying regeneration to other players. I plan to play around with that today when I get home from work.

If others could test and confirm this, that would be wonderful.
