Need Help playing support (Kiriko/Ana) - VOD reviews available

per title.

Gold 3

IGN - Cheesypuffs

Just finished my support placements (usually play tank) and placed gold 3.

I usually play tank in comp, as I like playing as a frontline/thick of it characters. However few bad habits seem to transfer when I play support, thus look clueless at times.

I enjoy playing Kiri because of her utility and mobility, but do pretty bad on her to the point where it looks like I'm throwing. I tend to be more comfortable playing on Ana.

Could use some pointers on how to play support more effectively. Linked some vod reviews below

W6RHZY - Dorado (this was a steamroll. didnt even cap 1st point). This one's egregious as I do a lot of silly stuff as the enemy team had an uncontested ashe and illari & none of our teammates were doing anything about it.

VXCCYX - Busan (swapped kiri after round 1 loss and got more value from ana and won the game)

ZHGJ2E - Eichenwalde (Kiri on attack, ana on defense)

Could use with some tips on how to play better (not really bothered about rank).

Thanks
