As a support I really don't like being the higher tier player used to balance out matches
I don't want to say that support is a useless role (some might), but it is not the kind of role that you can especially carry with. Some can and certain support champs can definitely carry but I play a more sustaining role. Games are frustrating when I am the highest mmr player on a team of, say, a casual trio and the players I am facing are all of my mmr. In most, if not all, of these cases my team ends up losing. I play how I would normally and I just go with the flow, but I can't give my players the support they need when their mechanics aren't as a good as the opposing teams. Anybody else experience this?
Edit: I am not necessarily saying I am a high tier player -I'm not - I'm just saying I don't like playing support and having the highest mmr on my team especially when the gap between mmr is large.

can empower and enable proficient players and teams, but they can't carry.
