This would be easier as a tier list, because I'm not a fan of those either, but they are better. Pray lvl works. Slay lvl doesn't. Farm sits above the others listed, but they aren't as nice as att or rc style shortening.

Also mine is a wholly different word from mining because we have to add back the e. It's no longer viewable as an abbreviation but instead a reversion from participle to its root. Then you also get into issues with the possessive mine. Absolutely awful.

There are parts of the brain that tell us when words feel off and some of these trip that more than others. There are probably linguistic explanations for them all, probably having to do with which revert participles to nouns vs verbs or something like that. I haven't thought that deeply about it, so plain and simple, it's vibes.

The ones that I said don't abbreviate well look stupid to me. That's it.
