Why Support is a dying Role
(This opinion is based on Diamond Elo Games)
Support is a boring and an ungrateful role. No matter what you do as support your teammates do not notice because you are expected to do your job right.
Nobody runs around screams "BEST SUPPORT!!!", they are more wowed by "double kill by Ezreal".
Nobody gives a fuck how many skills you blocked, how many thresh hooks you landed, because they will notice the two you missed.
The fact that you are always 5+ levels behind and never finished build is not pleasant.
Support is so unpopular that choosing 'fill' in DQ is 95% instant Support Role, while other lanes wait 6 Min in queues.
RIOT had a perfect formula in the end of season 5 and killed it in Season 6. The game is dying.
