If you’re fine with “affects only the caster” as meaning “affects the caster and others” then we disagree too much on that basic point for other points relevant to this topic to be meaningfully discussed in my opinion.
You asked for Range: Self spells, and those fit the bill. There is no separate definition I’ve found for “Range: Self (X)” spells in the rules. As far as I can tell, they count as “Range: Self” with added on info; they’re aren’t a separate ruleset.
Why do you think I think that??? When did I ever make any such claim?
Please don’t ask me to waste time defending positions I haven’t made.
