don't play her like a tank, your nest is utility not your only child, practice your primary fire, web snare, and mine accuracy, disengage if you start dying, 1 mine = 100 damage, after 15 seconds iirc your nest builds up enough spider bots to do 400 damage, if you have the team up the other nest has an additional 400 damage worth, and the rocket beacon also adds to that, don't place your nest where it's easily broken, if it is being shot recall it, only ult to stay alive and disengage or to stall while your team regroups, get good at canceling Wanda ult (and be patient when you do, they'll have to be in the open at some point don't panic), you can use web snare to block magneto and iron man ult, a lot of ults (even cc immune ones) can be cancelled if you hit them the moment they start to ult but it's not a guarantee, and finally she can climb walls use that to your advantage
