You all just know to define a summoners' behavior through KDA, your punishment system is really smart enough.
No, I'm verifying a judgement call that was made by others who were in the game with you using KDA, CS, wards placed, and death locations. Riot has more than that to verify with, but what's available is certainly incriminating enough.
Lets assume the first death through third death unhappy coincidences. That happens. But 0 CS until 7 minutes? Yeah, a lot of the time was walking back to lane, but even that's pushing it.
Your 4th death, where you got soloed by Tristana, you were at the enemy tower. Very close to if not in their tower range.
Your 5th death, you where behind the enemy tower. Even Tahm Kench can't carry you that far. This is the one Amumu assisted with, which is why I bring up warding (which, as Jubbinaut mentioned, there was no pink). Your first ward wasn't placed until after the 16 minute mark, well after these deaths and after you killed the enemy tower, so even if you were trying to get pressure on the turret (which is fine, need to win), you were doing so completely blind.
I mean, you've at least got to admit, it looks very, very incriminating. It certainly doesn't look anywhere near the performance of a mid Plat, or a Gold, or even a high Silver, and not because you're new to the champion. It looks like someone who hadn't played the game at all.
Draven is easy to do damage in teamfight for a new Draven?
Well, yes. Was for me anyway, and I'm a mage main.
