Fire the dude that thought 2+ Ranked is a good idea
League is a fun team game, no doubt about it. I love queuing with friends as much as the next person, but ranked is completely different. Now its easier to boost/carry others, and pretty soon there will be vast levels of skill gaps beyond all divisions.
I understand that from a business side you always want to improve and update your product, but this is not a good idea at all. Whoever pitched this and whoever approved it must have been drunk..
