Lookup my name and see for yourself? Better yet, click through a few random players history and you will noticed the same patterns appear where each person can have maps they favor. It’s not uncommon.
What about a dialog button to the winning team at the end of a match that lasted less than 5 minutes?
option 1: Rise my elo i won by drushing or outperforming the enemy team.
option 2: Please leave elo as it is, a player disconnected/smurf.
If most of the winning team vote for option 2, don’t change elo to neither team.
Simple as that. It prevents smurfing to a degree and also fixes my problem of randomly winning 3 matches in a row by such chance and rising to 1400 elo and than 100% losing the next actually played game. It happens now and then.
