Just to preface - I'm not a Reaper main nor an expert, most of this is just working from basic principles.

I also noticed that your backline (mostly Ana) was playing waaaaaay too safely and not contributing to damage/offense as much as they should. However, your tank was doing a lot of legwork to make up for it.

The notes I took were just for the first round on university.

00:00:52

• Didn't need to drop from highground, now you've got no cover and you're out of your effective range

00:01:16

• Not too bothered about how far forward you were (solid angle, could've held it and run away when you needed to), but turning so far around the corner that you can't just strafe back to cover instantly when you saw the lucio/soj is just careless - Need more caution when you're that deep
• Then, because you got chunked, you had to wait to get healed before going in again when you could've been in and out much more safely and ready to rejoin the fight when your team pushed

00:01:33

• I think you were just focusing on something else here which is fine but try to remember not to waste time shooting a soj from a million miles away - She will always out DPS you and can kill you really quickly
• I would say maybe just TP to the left-side corridor and angle from there instead of walking across with your team and risking taking poke

00:01:43

• Can't be TPing on half health man, just can't be doing that - Definitely not in full view of enemies
• You end up burning both of your CDs and forced your supports' to pay attention to you. If your supps hadn't been focusing you, they could've been healing your genji/wouldn't have had to use Suzu, etc. etc.
• I think you're trying to do your D.Va's job here and distract attention, but if you'd just waited, you'd see that she goes in through left-side corridor and takes a great angle, distracting enemies and taking space, which would've been the perfect chance for you to go in.
• Lessons: Don't TP if you aren't full-HP and try to pay attention to/play with your team more

00:02:52

• I like the initial angle here, but just need more awareness so that you can back off before you lose so much health
• Backing off earlier probably also would mean you wouldn't have had to burn wraith

00:03:53

• I see the vision and this was mostly just a mechanical error on the TP placement due to panic most likely but def could've been saved by using that ult a second earlier
• Mostly fine, maybe try TPing to your backline instead of toward enemy push? It looks like a gut reaction so not a huge issue

00:04:26

• Mostly a positioning thing here I think - You had the choice of staying right side with your Genji (D.Va, Lucio) or rotating to left side with D.Va (Soj, Moira)
• I think you panic here after the Lucio boop and wraith to whatever was in front of you (left side), but I think where you were was fine, just need better use of cover to avoid taking too much damage and stay there longer
• I don't think this is a winnable fight though, so no stress

00:05:18

• I really liked the approach to point through left side, contesting and killing tracer and then pushing deeper
• However, TPing in front of someone, especially soj, is a terrible idea

Overall, for University, i'd say you did OK, but big issues with:

1. Awareness of your team (where they are, what they're doing, etc.)
2. Awareness of enemy team
3. Playing your effective range
4. TPing in front of enemies

Hope this makes sense!
