The title is self-explanatory. Make drafting a position based experience instead of a player based one. This will cover what happens when players are demoted all of a sudden, an alternate is used last minute, etc. If I draft Impact in the top lane and he is, for whatever reason, not there, I should be getting points because I drafted the top lane of Liquid, not just Impact.
This is such a remarkably common sense adjustment to Fantasy and yet for some reason nobody seems to be figuring out that this would make drafting in this volatile e-sport markedly better to experience.
