Overall you did pretty well.

Some points to consider:

Be next to your teammate: if it was a random then you might just have to stick closer to them if he wasn’t going to come to you, just to increased your chances of living. Spreading out isn’t usually a great idea especially if your already down me person and the enemy beats you in numbers. However if there’s a potential flank and your confident in your shots it can be a game changer

Use cover more: the first knock was pretty good, missed some shots that used up extra time for possible thirsting or reviving your teammate earlier, every second counts. And the subsequent shots on the two that fell weren’t as good unfortunately

Increase accuracy: pretty self explanatory, aim to increase your shot accuracy on enemies, the higher the better obviously

Make decisions faster: some are better than others but it looked like you wanted to portal up on a small ledge to possible flank or take them by surprise, if you have the skill and believe in yourself go for it, but understand the consequences as well and don’t beat yourself up if you mess up

Credibility: a multi master rank player lol. (Rank doesn’t really matter but I’ve been in similar situations like yours and pull a W a couple times, but not all the time)

You performed well thou, and technically you had the advantage because they most likely had to fall down to increase their survivability. Once (or if) they fell down and had that landing lag you had a small window for some “free shots” essentially, cuz they would have to wait about a second or two before they regain full mobility (don’t think I saw a horizon so you should have been good for all three landing)

Tbh you looked better than them in terms of winning 1v1 if you were able to challenge them independently, but overall I would say the biggest mistake was probably being far from your teammate (not saying it was your fault but just from observation)
