• Giving up / going afk
• Fighting outnumbered / not retreating

For context, I played some tournaments from 2016-2019 competitively, and just casually since then, Grandmaster in (I think) 9 seasons total.

The number of "it's GG", "lost on draft", or someone saying "we lose anyways" when they decide to suicide bomb I've seen is insane. HotS might be one of the biggest catch-up games there are, where a single won teamfight can swing the game hard, going from a 3-level deficit to winning the game. But yeah if you just say "GG, afk" the game is 100% lost. I'm confident if you give it your all in all games, you could swing your winrate from 48% to 52% for example.

Fighting outnumbered. Teamplay is the way of the game. Unless you have some niche split-push, double soak strategy where you delay the objective as much as possible, teamfights are where it's at:

• Don't engage a full-on teamfight outnumbered. Take your loss at the objective and just get camps, soak and get back ahead.
• If there's no reason to (keep) fight(ing), retreat. Got their fort/keep? Get out.
• Retreat when your (especially) your healer dies in a fight, particularly when early and you have a chance to retreat safely. If you can pick off one of theirs with a good chance, of course stay and fight.

That's all. 20-30% of the games I lose is because of one of these reasons
