I haven’t had a loss streak like this in AoE2 1v1 (I have in TG) but I do remember having these when I played DotA2 10 years or so ago.
The desire to finish the day on a win, yet I couldn’t get a win, and probably played increasingly worse each game due to anger and frustration.
I think in AoE2 1v1 I’ve had a win streak of 5 and a loss streak of 2 (less than 50 games though).
In TGs I think I’ve had a win streak of 7 or 8 and a loss streak of 6 or 7.
in TGs you have less control over the outcome of your team, but in 1v1 it’s solely up to you.
Makes it much easier to identify and fix/learn from mistakes.
Each game I lost since I started playing 1v1 again recently I made at least one easily identifiable mistake that largely contributed to the loss, and I always watch every replay after each game – I recommend the same, try and figure out why you lost each game and it’s also helpful to pick up on good things that your opponent did that you can learn from.
