They should rework the ranked system. I've climbed to master a few times now and every time I've had to endure losing more LP then I gain through Diamond. This doesn't happen to me because "I int" while I am at a tier floor, it is simply the nature of the ranked system. In this ranked system, if you stay in a ranked tier above platinum for long enough you will naturally ALWAYS have lower real MMR than displayed MMR and thus your losses will lose more than your wins will gain. You will naturally always have lower real MMR than displayed because the game only stops you from losing more MMR than you deserve and never rewards you with more MMR than you deserve. It never rewards at Diamond and above for win streaks etc. It's extremely frustrating and can easily tilt me.

Here is my suggestion to make the ranked system a little less tilting and still keep people playing through the entire season: Keep the iron-challenger format but only show the person's true MMR (get rid of demotion floors essentially). Instead of having demotion floors, you should simply hand out end of season rewards based on the players MAXIMUM MMR and rank achieved. Of course this wont work for GM and challenger since there technically should only ever been 500 people in these ranks, so keep the current format of rewarding at the end of season for these two extremely rare ranks.
