If 3 people have died already then popping your ult (late) and going for a “hero play” is not the correct choice. Sure if it works you’ll get endorsed for it, but 99% of the time it doesn’t work and then you’ve thrown.
Similarly, learn to back up or retreat from a lost fight. Giving the enemy even more ult charge isn’t worth it.
Learn when you’ve lost a fight, regroup, try again next time. Stupidity isn’t the same as glory.
If we lose one and the engagement hasn’t even began yet then I just backup and wait and watch usually 1 or 2 more just feed to the enemy team, its infuriating, also part of the reason I fucking hate Widow
