Those aren't facts, those are lazy arguments that prove you don't really know what you're talking about. Not attacking you or anything, I think even you would probably admit you're not the number 1 MLS fan or really know a ton about it.
MLS fans or not, it's just about the truth, data and reality. MLS has some big stars, great parity, decent academies and they are in hyper growth mode right now.

I don't know a ton about these leagues in Tier 4 tbh
12-15 seems quite accurate.
What's interesting is MLS is catching up to a lot of these leagues in quality, but by 2024(?) MLS will have 28 teams. So when MLS is on par or slightly above them in quality, they will seemingly "rocket" by them as they will have passed them in not only quality but also quantity, as they will have double the amount of teams as some of these leagues. LIGA MX for example has 18 teams and MLS will have 28 with additions of Inter Miami, Nashville and Auston and 1 more team.
My honest prediction, MLS will be in Tier 3 A (8th-12th in the world) within the next 2 years. MLS has a legitimate chance to be in Tier 2 within the next 5-6 years. There are factors that will help determine this such as the MLS academies, their continued hyper growth (when will they plateau?) , T.V deals, NYCFC and New England stadium deals, the global economy etc.
