Sets in Strongholds - Why Sentinel is the only tradeable/medable?

[Brannigan]

I could see a massive eruption of nerd rage if Sentinel gear became U/U.

It'd be pretty justified considering the drop rates and the fact that that gear would be complete garbage without being able to attach materia.

p.s. dear SE please let U/U meld materia love will brannigan

I guess the only thing that makes sense is they don't want to make crafted gear totally useless, because that's what most pieces of that gear would do if they were able to be socketed.

Instead, dropped gear is useless. Hoo-ray.
