As a Support main, I couldn't give a damn about your KDA. There is one thing I noticed, however, that caught my attention almost immediately.
USE YOUR DAMN WARDS!!!
Your vision score is atrocious, in ALL OF YOUR GAMES!!!
You have multiple games where you've had 2 stacks of FREE WARDS on your trinket for 14+ minutes of the game. (i.e The entirety of the game)
Like, come on! Place them in the lane bushes. Place them in the dragon pit. Hell, place them behind your team's buff entrance, for all I care. Just place the damn wards!
I'm sorry if I sound like I'm attacking you, because that isn't my intention. But you seriously need to get your vision score up, if you plan to get out of Silver as a Support main. (And, honestly, as any role main, at this point.)
Your average Vision score is 28.1, your average Control Ward placement @ 15 minutes MATCHES your Control Wards bought...One...which is a problem in itself.
Again, this isn't me attacking you, personally. But the Support in me is screaming, at the sight of your vision score.
