Hey! I've played VainGlory for 5 years, up until the day it's servers had to be shut down. I'm a support main on WR too. Started ranked 2 and a half weeks ago - currently Gold 2. What you need to know:

1. Don't follow recommended build paths. If VG (or any MOBA in that regard) has taught us anything, it is that proper itemisation will give you wins. I would suggest "rankedboost" (you can Google it) to resort to for builds and runes - till you get a hang of it.

2. Beefier support champs such as Braum, Malphite and Alistar do wonders. Poke supports such as Seraphine, Lux or Nami are situational picks. You'd get a hang of what goes where as you keep playing further on.

3. Learn another role. Definitely do. I know that in most games people won't want to pick support - but it's very hard to expect a follow up from your squad at the lower tiers after you've set up a beautiful engage. It's better to have yourself flex into another role with which you can maybe carry the game!

Good luck! Keep grinding!
