Most players would take mid over support role anyday. This is due to the fact that most adc's, instead of thanking their support, who helped with that double kill, will just say:

"omg you almost ksed me. be more careful. give me that blue buff.".

In the case of being caught out and trying your best to help your adc, there will often be three outcomes; the two common ones are:

  1. ) your adc and you get killed, even though you tried your best. "omg report noob support cant heal",
  2. ) your adc survives and you get killed, the adc will usually say "wow feeding noob report", or
  3. ) they focus your adc and you try your best, "OMG NOOB!!!!! WHY DONT YOU GO IN AND HELP WOW. REPORT IM AFK #YOLO".

If the support accidentally kses (if you purposely ks them, I will pee on your dog), the adc will usually say "wow reported", instead, the adc should just be cool with it, since this is just one game; you can have other games where you get 20/0 VayneSquare Vayne and a penta with CaitlynSquare Caitlyn.

This is one of the reasons why support isn't played that much; so whenever you're adc and have a support; remember to thank them and not get so mad at them, so people will actually enjoy supporting sometimes.
