The two mechanics look and function differently, but it is handled exactly the same way and the result from doing the mechanic correctly is swapping one debuff with another to prevent death (crazy that failing the one in WoD still oneshots me @80 lol) I'd say the difference is that with moonbabe, you'll have to repeat it at least twice to prevent the stacks from getting to 5 during its phase.
The stacking of mechanics is something the OP will have to get used to. I believe it's around here that mechanics in NM starts utilizing the background more as well. I bounced like a trampoline during my first Susaku fight.
