Your unnecessary showboating cost you the game
The copycat mentality of League means people just mimic other people without understanding when it's appropriate or even right to do. This is what leads a lot of people to dump a million Luftwaffe N-bombs into the chat for no reason other than because they saw some inbred fuckhead on Twitch with %%%%FISTER in his name do it, then wonder why they get permabanned minutes after the match ends.
In this case, I see everyone on my team dance in front of the nexus and flap their mastery and emote dicks at the enemy and let the minions whittle it down. I also see them dive the enemy fountain for no goddamn reason, giving the enemy a chance at a second wind.
They got a second wind. And baron buff. And pushed six turrets, an inhibitor and destroyed our nexus. All because the team wanted to showboat. The only person trying to destroy the nexus was me, and I was Support Rakan.
In our previous game, the enemy Gangplank would just constantly flap his mastery dick at us. He cost his team the game by doing it CONSTANTLY, at the most inappropriate times and getting constantly caught out for it.
All your dumbass showboating does is make you look like a moron when it blows up in your face, and I'm seeing it happen more often as we're getting into the third generation of mindless copycatting.
