So the problem is that there are too many people in D4 and thus there is too big a skill discrepancy between such small differences in rank with D4 feeling like a black hole because of low lp gains.
My solution is pretty simple, why not just add a 5th Division to each tier? I know it might be difficult to implement and I know players just LOVE the current system(xd), but I am sure tons of players in D4 would drop to the new "D5" and with this you can have a more spread out system because there are more tiers. I know this might make it more "grind-y" on the surface, but promoting with a 65% winrate into D4 after gaining 23-25 a game only to suddenly gain 15-16 a win seems more grind-y to me.
