My thoughts and questions on the job:
-I think the overall job design is good. It's like a mix of ARR-HW NIN and MNK.
-Does an affliction's effect time reset when you add a stack?
-Can you have all three affliction on a target or does a new affliction remove the older one?
-Does Siren's Path's affliction just increase damage you do to the affected or does it increase all damage done onto the affected (like from other partymembers)?
-I don't think Umbral Movement needs partymember movement effect. I think every melee-ranged job gets a gap-closer, plus it could potentially mess up some mechanics where you need to stack then spread/go to specific spots.
-Shared Pain's description is a little confusing. Does it take away 10 affliction stacks from a target and make you invulnerable to them?
