Not EVERYTHING is snowbally.
So I know there are lots of complaints right now. I really do get it. I however have been having a few decently long games.
Especially one I just did a little while ago. It went 55 minutes long. Fiora (me) vs. Trynd on top, our Kog vs. Kass on mid, our Jinx & Lux vs. Twitch and Teemo.
By 28 minutes the enemy team had 24 kills to our 11 kills, we were 12k gold down, down 5 turrets, down 2 inhibs, and behind by 1 dragon. We only had 1 drag and 2 turrets at that point in the game. Over the next 27 minutes of the game we managed to hold on and eventually win through lategame power. So it is possible to hold on if you completely lose early game. It did help though that we stole 2/3 barons after that 28 minute mark, and the 3rd baron we killed them all for it and won.
Though once those minion buffs get added I'm not sure if we would have won. We had good wave clear though.
Beyond this game I had other games that weren't over quickly and we played it out.
