I can't have a clue from those photos. I can only go on what you say. I don't know how they arrived and what you've done to them since then. You say you cased them up and then let them dry and then recased. That'll often screw your leaf for good. All I've got is you saying you know how to case and that it's the leaf, not you, but that you're not sure. I can say though, as marcl often says, case only at the time and when it's ready, roll with it. That usually means start casing the day before you bunch or roll. If you get damp leaf out of the bag, you have to try to deal with that specific, uh, "case." Sometimes if you pre-case and recase, the leaf goes on awesome, everything's groovy, and a week later everything's disintegrating and falling apart.
If I just saw those photos with no words attached, and assumed they looked like that out of the bag, I'd say, Fuck, and maybe toss it, depending on my mood. When this used to happen with WLT leaf, I'd show photos on the forum and everyone would be like, "Oh, hey, no problem, it looks awesome to me. Bind with it or at least use it as filler," which is what you're asking about. I'd be so fucking pissed I'd just chuck it, thinking, "I fucking bought binder, not filler." Later, I started burn testing it, and if it burned well and smelled great, I'd use it as filler. I'm still figuring this shit out after five years.
