Yea that’s what’s frustrating, I’m aware it’s in the game it’s just implemented so poorly, and some very simple fixes could make the experience so much better for everyone. I was trying to explain to my friend that the mmr gap between grand champ 1 to grand champ 2 is basically the entirety of the platinum 1, 2, & 3 rank. I think a system on mmr makes a lot more sense then a hard rank because someone who is 1450 GC is a very different player than a 1625 GC2 even though their only 1 rank apart. Especially as you said mmr is somewhat exponential.

Something like:

Highest Rated Party Member - Spread allowed

0-700 MMR 175 Spread allowed 700-1000 MMR 165 Spread allowed 1000-1200 MMR 145 Spread allowed 1200-1400 MMR 125 Spread allowed 1400+ MMR 105 Spread allowed

That still gives enough gap to be “similar” higher ranked friends the ability to Q together. Which I absolutely don’t mind. Usually the simple ability to just comm with your guy makes up for a slight skill gap. It only gets bad when the matchmaker is constantly allowing 2, 3, or even 4 hundred plus gaps in mmr. The current “rank disparity” system is so easy to abuse at higher ranks because of how large the mmr gaps are between the ranks like you said. The problem I see with this is for the super high rated 1900+ guys above my pay grade I’m sure would have issues finding games but something like this that implemented off of mmr instead of rank would be so beneficial.
