Added, can prob help u out. I'm a Mid main, jungle and support secondary. Platinum.
I see you have a Plat fellow helping you out so I doubt you need me, but if you want, I can help. Only Silver right now, but here if you need it.
I added you, I can safely say I climbed through bronze-plat while playing support seeing as it is my best role.
Hey BrisBoosted, i added you in game.
Thanks peeps ^_^
