Malignance is great, but its lack of Def and MDB in particular make it a liability in some fights.
Namely sortie basement bosses, Bumba, some other V25s.
In those fights you need a couple pieces that are heavier on the def/MDB side. Previously that was only Nyame and you take the hit on DPS because you need it to survive.
The new gear gives you an option that is very heavy on Def/MDB and still great dps wise on top of that.
When are you using nin in any fight like that is a different question.
