Ive been picking up Illari alongside Zen for support and Ive been doing really good with her? Her Pylon+Beam healing is just really good and sometimes I get like a really good kill with her while shooting people on a whim? Also it helps that she actually has good movement and that makes her pretty useful compared to Zen in certain situations. And I even got a potg with her!
shoutout to the sombra who pinged me that their ultimates were ready and waited for me so that we can combo our ults together
