Personally I don't think they're all that powerful in terms of a retcon run (and that /is/ how I'm viewing them, as they're retcon rewards).
You're pretty much the only one to feel that way.
If you disagree with my opinion, that's fine, but there's no definitive this is right or this is wrong in this situation.
Opinions aren't some magical construct that are immune to cold, harsh reality. It could be your opinion that the sun revolves around the earth, or your opinion that dinosaurs were wiped out by time traveling aliens, but you'd be wrong. Instead of hiding behind opinion like it's some kind of shield, how about you back it up with something?
Here, I'll even give you a start:
In a run where you're using ranged weapons, what non-donation hat is better than Mecha Nist's helmet for general retcon use?
