Solving The 4-man Epidemic
Hi! I have a hunch that those of you being matched with 4-man premades often are matched thusly because of your role choice. From my experience, Support and ADC are the hardest roles to play without a coordinated team, followed shortly by Jungler.
By contrast, most solo players don't like coordinating with teammates and/or want to show off their mad carry skillz!11!
It follows that more support, ADC, and jungle mains would gravitate toward premades, filling those 'slots', while toplaners and midlaners would be more likely to go it solo, being chosen to fill the remaining slots. Let's poll it out for SCIENCE!
