Issue with support is a symptom of a larger problem: champions that aren't any good at being damage dealers are not nearly as fun to play, and in fact, outside of high elo, can be really frustrating to play as, especially in solo que. Why? They have little ability to make individual plays that affect the course of the game. Sure, when they are with allies that have some actual game sense they can be formidable, especially in the hands of a good player. But that's a dependency that damage dealers don't really have, and more than that, many damage dealers still bring decent utility to the table. Which means that pure tanks and pure utility mages are increasingly being pushed out of viability (especially in lower elos). I'm not sure what the exact solution will look like, but something's gotta give for those archetypes so that they can have some ability to make individual plays (at least as a fallback from their preferred teamplay patterns).
