I feel it's hard to get players to go for the support role, and I feel that it is a major problem for Riot. I been playing league for at least 4 years now, and playing support has always seemed like the less appealing role. I think the problem lays in lack of diversity, all to many of the supports feel the same when playing them. I would like if Riot made a support who could chance form like nidalee, which would give the player more opitunities, i know this sounds broken and strong, but if you removed the champions ability to autoattack it could end up balanced.
Have a nice day everyone
