If you're talking about SR (Im guessing you are since everyone seems clueless on how you got here), you shouldnt be picking up kills at all, since that would be actively taking gold from your higher damage carries while at the same time resetting your own personal gold value, which isnt really a good thing since your often easier to kill with your limited item selection.
In terms of which supports can take a more active role in the SR game, without becoming sustain bots though, I'd suggest Blitz or Leona, who fufill a much different niche, and act as strong core initators on a lineup and can be played more aggressively.
I would still try and hold back however and make sure youre not last hitting those low health targets if you can, just to keep the gold flowing on your carries.
