First things first. I absolutely know she is overtuned and needs adjustments.
BUT
I would rather fight a Juno Brig every game than sth like Bap, Kiri or Ana absolutely sucking the soul out of every meta they are in.
Juno definitely has some of the least frustration generating abilities of all supports.
No Nade
No Lamp
No Suzu
I think the Juno problem is exacerbated by how overtuned the tank role is
Tank stats are way too high and then you got this Juno bih speeding them around every 8 seconds. Brainrot
kirikos kit feels like it was designed to suck the fun out of the game
As a DPS player I dislike Juno’s anti-projectile mobility far more than a few cooldowns that are easy to bait.
As much as people whine about them, I have benefited more from Bap and Kiriko being in my team that I had ever issues dealing with their cooldowns.
Yea. I am fine with her being the best support. Sure it’s nice to have variety, which we certainly do outside of the very top of comp. But not playing into cc or invulnerability skills is nice.
My problem with Juno is the sheer value of movement speed used during fights.
The reason speed boosts like Lucios amp and JQs shout are okay is because theyre more often used as gap closers, or ways to kite out of fights, and misusing them means LOSING on other value, like to save yourself with overhealth, or improved healing in fights.
But Juno speed is used almost exclusively as a dueling tool, and loses nothing for using it in that way. People somehow dont understand just how insanely strong movement speed is in fights, and its going to keep her meta, especially when combo’s with the ult she has.
I want to like Juno, and sure I suppose I like it better than Lamp, but thats more to do with my innate hatred of all things immortality in OW. Generally I think I just dont like Juno’s impact on the game.
Im tired of every last fight being in double speed. It just isnt interesting or enjoyable.
she felt to me like “Lets make a dps hero by heart and add a primary healing to attract dps player”
it worked. 
or more like, “lets make her a dps hero with the benefits of beeing support”
I don’t think a support being effectively invulnerable to projectile dps and forcing hitscans to reliably deal with her is healthy.
I mean her and Illari are pretty obviously A-10 Warthog characters. The gun was made and people thought “now how do we design something around this gun?”
can’t speak for illari, she feels wierd to me.
but my friend loves her and he also likes kiriko.
Illari just to me feels onedimensional unlike kiriko who heals, throws kunais, waits for a play by the enemy to block with suzu, harass and escape while climbing walls.
illari does like 1 jump, throws a pilon and spams primary. (I can’t give illari justice)
