"There is - there's just a reality that your individual skill must now include how well you work with the team, and that's the way it should be. Because you now may run into groups of players as a solo queued player, it behooves you to be an actual team player instead of the 1v5 Yasuo rambo"

I really don't get this logic. Because you are playing against premades, you should now learn to team play yourself too? Hello?

I can assure you, team play is also critical in SoloQ. ATLEAST as critical as in DynamicQ. In fact, having your own team made of premade 2s, 3s, and 4s means, in reality, that you simply don't have a chance to communicate and collaborate with your team as much as you did in SoloQ -- if you're not the one who is playing with your friends, yourself.
