As far as i can tell, nobody enjoys this game mode. Maybe a small portion of the playerbase, but most seem to hate it and resent being forced to play it to get the rewards. Tier 10 meta is by far the worst it has ever been (i am playing NA) and in ranked this gets just exacerbated. I think it is for balance data collection that they put this game mode in more than anything.
Back in the early days of ranked, i remember seeing more consistently the best players being at the higher ranks in my games. Now i am seeing very mediocre players on very high ranks not because they are good but because they figured how to play the system. The current system encourages a high level of cowardice which makes games really really garbage.
