No, I don't see why that would be important.
Vice versa, you seem to be unable to see my point.
You reject the idea of a 'true' competitive ranking system for those who want to compare themselves on the highest levels, even as a coexisting thing to what we currently have, simply because you think it wouldn't be a fun thing for the common player to enjoy?
Why not have a competitive ranking system? In a true ranking system, top players would finally start caring about being ranked again. That's the ONLY purpose of ranking people.
It doesn't truly matter for the Novice/Beginner/Intermediate where he stands on it, if he doesn't want to be competitive.
If the ranking system was true, then ranks would actually matter again for those who care. You cannot tell me, that the Intermediate/Expert has anything meaningful to say about the ranking system. He hasn't even come close to experiencing it to its fullest. He's having fun, and that's great.
Nothing changes for the common player, right? What would they actually lose? They can have their fun on their playground - hell, I'd join them too!
But we do need to have a true competitive leaderboard, otherwise you could just get rid of it.
If you can't see that point, then I don't have to waste anymore words to this conversation, sorry.
