Reason why Season 6 is so casual
Riot does not play Ranked. Simple as that.
Riot is a room full of casuals who cannot climb over Gold(and under) and see absolutely no point of any competitive and reasonable game changes.
This is why we see Plat 1s having Gold 4s in their rounds. This is why we have Diamond Promos and you have Gold 3 junglers. This is why we have Dynamic Queue and DQ Legal Boosting service.
These changes are made by non-competitive casual players like most of Riot's Employees.
