Plat Support Main LF Team/Duo

I am a Plat Support main , I have been Plat for 3 seasons, Highest Plat 2 and currently Plat 5. I can play any support effieciently EXCEPT for Alistar, Zyra and Taric(I can play them okay) . I believe if I can keep a member of the time alive that can make a big play or be more beneficial I will gladly sacrifice for the greater good.
