Any ADC losing the game is automatically the Supports fault!

So just wanted to put this out... Bronze division here, Nami support main (it's the only role I play I just don't play ranked often, secondary ADC which is about 1/50 games).

Just had a game alongside Ezreal. I got him first blood with aqua prison, and his second, third, fourth and fifth kill. He then started to lose and complained it was all my fault. Said I can't ward (33 wards + 6 control wards in 39 minutes) while was lowest on the team at 8 wards, 0 control. He ended the game with nearly 2k gold, and kept pushing a lane alone (against Yasuo, Draven and Jax) but of course it was my fault he was losing. I had 64%KP vs his 56%, but again - my fault he was losing.

Then I decided to look at his runes... mostly tier 2 runes (no big deal there I think but tier 3 helps a lot more) and saw this for his stats: 7.7AP, 3.37 Magic Pen, 0.05 MR/level, 2% AS, .2% CDR, 0.08 AD/lvl, .1 Mana/5s, 1.17 Mana/lvl, 0.03 Health/5s, 0.97AP/lvl and not even a filled rune page. Running warlords, on a champion he has a whopping 5 games with, and no mastery level. While I'm sitting at level 6 Nami with 2 tokens (just need that 3rd S/S+, I keep getting S-)

But of course, it's all my fault. Not his choices to run Ezreal solo with no vision. Not his choice to not ward, and certainly not his choices to act like we are playing bots, it was my fault, I admit it.

I know I didn't play perfect, I know I belong at low ELO (I climb when I play more often, 62.5% winrate on Nami ranked) but I also know that bad players love blaming everybody but themselves. Nothing important here, just wanted to get it out and laugh some at the fact he had no idea what he was doing yet it was still entirely my fault.
