Even further overspecialization: Making the support do absolutely everything
The community has once again, FURTHER quintupled down on wanting to only teamfight while granting the enemy team every fucking possible advantage in the universe. Once again, the support is expected to not just push, defend, go for objectives, peel, tank, provide buffs and crowd control to the entire team at any given time at all times regardless of distance, ward, and ward bust among 50,000 other tasks expected to be performed perfectly at with absolutely NO failures, but they're now expected to lead the charge on every fight, do more damage than the champions that do nothing else BUT damage, heal, shield, apply grievous wounds, on top of another 50,000 tasks that they are expected to perform better than anyone else without fail at all times.
But now nobody wants to even do that one tiny little thing they wanted to focus so exclusively on. The support is effectively pulling all of the weight and performing all of the jobs because nobody else wants to do them. And if that wasn't bad enough, now the community is actively trying to get rid of all the supports.
