The support role doesn't need changes more than any other role. Stop complaining
I'm tired of people complaining that the support role is "boring" and "lacks impact." Just because you aren't getting kills left and right doesn't mean we somehow have to fix the role. Support is meant to be the perfect role for the unsung hero types, those who love to help and don't really ask for recognition. Personally, I'm the kind of guy who would rather be 0/10/20 than 10/0/0. However, people who love going on killing sprees and carrying their teams are constantly complaining that the support role is meaningless. Supports are a strong hidden power, helping the team from behind closed doors. They aren't the action heroes going in guns-blazing, and they shouldn't be.
TL;DR The support role shouldn't be changed to be more "exciting" or anything. Its rightfully a niche playstyle, and if you don't enjoy it, its not the fault of the playstyle.
