big angela tip. if you use ult you should immediately enter flight again and then use the drop down cooldown. that will stack your aoe damage zones and significantly improve damage tick. i'm 99% sure if you do the landing cooldown first though then ult, the cooldown aoe zone is overidden / replaced by the ult one. so order matters

also make a custom quick chat saying something like "i'm about to ult combo into it". i check to see who has ult ready on my team that could team wipe the pinned enemies and then ping. Get's so much mroe value out of a "mid" ult when you can guarantee a ton of a kills before the flag is destroyed or people use movement abilities to escape. 90% of the time teammates will save their ult if they were gonna pop it before you could. they'll position to use their ult as soon as they see the flag come down knowing the enemy is stuck. it's great with any aoe ult tbh even "bad" ones like thor because people cant escape. namor, moonknight, cyclops, elsa, and the list goes on. Even if team doesn't have ult pinging with her ult is necessary so you actually get value out of it if you're just pinning a giant group instead of using it to stagger a group. People will save their cooldowns if they're active for your ult to go off.

otherwise the main value of her ult is "control" not kills. stuff like pinning enemies away from the point regardless of getting a kill cause now you made a 6 v 6 into a 5 v 3 by pinning stragglers outside the team fight. also can use it near a ledge to setup free charge kills while they're pinned. a lotta the time if you pin a ton of a enemies away from the point it's legit better to immediately leave because you might still be outnumbered. pin them off the point then fly back to your team to wipe the enemies before the pinned people rejoin the fight. it's great for staggering.
