Win a 4v5. "You guys suck"
Just won an ARAM game where our blitz was DCed the entire time. I was playing Veigar and The enemy team kept saying how we sucked during the game. We ended up winning and they continued their trash talk at the postgame lobby.
"You all sucked. The only reason you won is because Veigar has so much zoning CC and damages in his kit"
I'm not even going to comment on how stupid it is to say the other team sucked when you lost 5v4, But I mean, I'd be the first one to tell you that everyone is wrong about Veigar being terrible (even if you don't stun them his E it's like a J4 ulti on a 9 second CD), but I just find it's amazing how quickly everyone changes their opinion whenever Veigar does good.
