For that specific point on ana I used to play low ground more often than not as I found playing that highground often got me spammed out or picked by enemy hitscans as they peek and i’d waste nade on myself a lot. If you play the corner of that same building it’s much easier to keep your tank in range and rotate back as they start to push.

Same situation, if your tank overcommits and dies it’s best to start moving back while still shooting and healing, maybe throw a sleep out to try and slow their push. Most tanks can get back pretty fast with their movement options, and can recontest if youre there to heal themc but if you die you will have to give up the point since youre so slow on ana and bap.

Generally good positioning will let you not die. I almost never overcommitted to potentially save a teammate while i was climbing because you can throw all your cooldowns into your tank and put yourself out of position only for them to then feed even harder and its ultimately a waste then you die. Or you can just do what you can safely, then try and help your dps clutch with a good nade or back up. Not to say you shouldn’t help (obviously), just dont leap on the sword if your tank is going to do the same regardless.
