why does turret siege require a team
It's entirely possible to complete the requirements in a normal game and doesn't require any absurd picks.
If the idea was that you are supposed to do it intentionally regardless of the pacing of the game by refusing to take a tower down until another lane can also take a tower down, then it would be a reportable offense from the enemy team for ruining game quality (like afk'ing for extended periods of time, which teams have been reported and punished for by the enemy team despite all 5 members of the "afk" team agreeing on the tactic).
