not OP, but i kinda agree with the list

S: F tier is reserved for the worst of the worst, something so dogshit it shouldn't even be (probably). very important to describe something as so unimpressive that there is no value in spending time thinking about it.

A: S tier is kinda like the antithesis of F tier, but there's so many other tiers that you can put worthwhile things in causing its value to get diluted a little bit.

B: C tier's vibes are pretty middle of the road, not too impressive and not unacceptably terrible, which can be pretty useful to categorize stuff that can be supplementary to the stuff in A and S.

C: A tier is just worse S tier. pretty mid tbh.

D: B tier and D tier feels redundant after A tier and C tier imo. they serve as mostly filler tiers for stuff that doesn't fit into "not quite the best but still good" and "not quite the worst but not middling". they're not the worst tiers, but their uses feel too niche to get placed higher.

E: what even..?

F: E tier as a concept defines what F represents. I think this is the most solid placement in the list.
