For years you could do two heavy cleave attacks with the old version of the talent and now its no longer possible.
When using cloak of pain and then attacking with dual wield cleave attacks it makes cloak of pain instantly use both parts of the stealth which means you now no longer get a second stealth.
I think it works with all cleave attacks? Things like this are why beta tests are important because shade isnt worth playing in this state. If this is intended then all i have to say is the balance devs took another step backwards regarding shade balance.
