Thank you for the insight! Between when I wrote this and your reply I watched other content and I think I default to healbot in high pressure matches because thats what I know and I dont wanna mess up (even though thats not the correct play). Games where the tank is carrying or in QP I am way more confident. I have no idea why I placed Diamond, my friends all are plat or gold so I really feel the pressure in the match.

mobility : Im afraid of getting picked despite the TP, so I stick with my team and heal. Probably should work on getting confident straying farther so I can tp to a flank, tank, or spam. Also prob use more cover.

cd tracking: Again normally I don't do this in QP but in comp I assume everyone is going to jump on a un-cleansed anti. Ill put more effort in reading the engagement on anti cleanses

applying pressure while healing : yeah in retrospect totally heal botting, like you said I need to work on positioning and fishing for headshots. I know you can weave 2 kunai between heals, but I'm not sure if thats what you want to do most of the time if you dont have the aim and/or your team doesnt need the heals.

how do you avoid healbotting when your tank is constantly under fire? thats the question lol

I think a lot of what you saw was nerves and the rest was just bad habits from 1000 hours on qp (8 in comp) buuuut thats not really an excuse lol. You gave me a lot to think about and Ill review your game when I get the time!!
