Respect for you, too <3
On the salaries point, I don't try to find any extra information. Certainly nothing is handed to me in that regard as a caster and I don't go looking for it. I probably get salary info from the same places you do (RIP ESPN).
There is more breakdown that could be done on style-of-imports, to be fair. For example, right now no self-respecting LCS or LEC team imports players who don't speak English anymore. This used to happen. It was bad. They never worked out. The coaches/GMs did a bad job vetting and understanding language barriers. So through that lens, by default LCS teams need to be English-speaking, unless you could get together a roster like huhi+Pobelter, any other Korean-American or Korean-Canadian players and some more Korean imports who may not speak English. That would absolutely move the landscape around.
