I think Juno's another support I want to start practicing, I tried practicing her and she was super fun! I really love her right click move although I have a habit of spamming it everytime it's not on cool down, I think you need to space her moves a lot to get the most out of her (Although thats a problem I have with almost all other characters, using my abilities all at the same time usually out of panic). I always wanted to play a flying character but I just couldn't click with them, but Juno definitely does. Her ult was a bit confusing, but it's really good for pushes
Zenyatta+Juno combo is also insane, giving the Zen more speed with hyper ring and having two HUGE aoe healing ultimates is insane and I think as a Zen main I would love playing with her on my teams
Also also, her voicelines about being scared and anxious like YES, I too forget to breathe cause I get too scared of things fucking anxiety (self deprication)
