Did I miss some double-AD carry meta change? Your game has two AD ranged on each team, and I might have seen 2-3 enemy teams yesterday that had it.
Also on your Ashe note, I feel like one of the single biggest problems in super low ELO games is people going alone. It doesn't matter if you had a ward, it doesn't matter if you just saw 3-5 enemies in the bush, in the jungle, about 5 seconds ago. It doesn't matter if you literally get 6 "RUN AWAY" pings as you are walking alone into the jungle. You will still go alone, into the jungle, with 4 people missing, and then you will instantly die since, shockingly, those 4 people are still in the same place.
