Remove the support role and have 4v4 instead or possibly introduce a new 4v4 map
One person each lane and a jungler. Now no one is asked to do a job that a bunch of people clearly can care less to do. Queue times for dynamic queue, solo queue (better reinstate this asap by the way) would be wonderfully short. One less person to decide who he wants to play and less time drafting a team together. Cleaning up some of the inventory or the possiblity of more items with utility that can make up for the absence of the support role or even the return of certain wards? Hey do you go with damage or do you go for that ZZ portal and leave ya lane to help out in another? Sometimes you can do more with less.
As a kid, I hated when teachers gave me multiple ways to solve out a math problem and they wanted you to use the long drawn out method to understand the material. I understand know what there were trying to do but once its figured out I want to use the method that going to have me answer to that equation quicker and more efficiently. Coming up with all these new fancy complicated algorithms about who does what and where is moot. Just keep it simple......Don't you agree?
