Unpopular opinion: a close loss is a better evening than five easy wins

I know the point is to win. Before somebody quotes just the title, I am still going to repair the objective and try to stop yours.

But the rounds I remember are the ones where both teams had a chance. Trading the same doorway, finally getting through with ten seconds left, losing because the other team made one good decision. Five rounds of walking over a team that cannot leave spawn are technically successful and completely forgettable.

Where I get stuck is what to do about it. Switching teams can help, but switching every time your side starts winning feels patronising too. And sometimes the losing team is one organised push away from turning it around.

Not asking for a new server rule here. I just want to know how people recognise the difference between a tough round worth playing out and a team balance problem that is making everyone miserable.
