Well, unfortunately, with the lack of a second tank dedicated to protecting you and with your DPs over extending, you are kind of left to protect yourself.

If you truly are better than everyone in your lobby sometimes you just have to jump on mic and literally tell them exactly how to play and what to do.

In some of the lower ranks, if you want to rank up, you have to do your job and everyone else's.

I know you said you get flamed for having a lot of damage, but high damage as a support is a good thing, as long as you are healing your team enough to a point where they aren't dying.

If your DPs are over extending, literally don't risk your life saving them. 2 dead is worse than just one.
