The problem is that every game has a losing team, and the players are supposed to feel bad no matter how well they performed. "Defeat" or "Loss" messages, sad music, sinking stats, public match record showing off your failure; there's punishment baked into this model of game.
Trying to keep players by throwing them easy wins is an insult. You're the game developer that created this "winner/loser" model to begin with. Now you're trying to make me feel better with this bullshit? You're the one that caused the pain to begin with.
It's absolutely a cheap way to give you an easy win. If I get SVP but lose in overtime, it's absolutely an insult to throw me into a bot match for 'practice'
