It doesn’t feel great when you have a Juno on your team whatever role you’re playing. If you’re a tank and the other team doesn’t have a Juno, unless you and your dps is in tip top shape, you know you’re going to get less heals/survivability the less you and the dps do in terms of damage, which is hard to do when the other team is popping out purps, immortality field, discord orb, etc. Juno gives you speed, but what’s that going to do against all that.
As a DPS, same thing. You’re about to die? Mercy flies over faster. Baptiste will throw you a bone. Ana will snipe you. Kiriko will throw you some incense. Heck, even Brig will throw you a pack. Also, Lucio is better because his healing/speed is constant. For example, Juno has to either pick to shoot or heal. Lucio can heal and shoot, not to mention his skill is aoe, and he has a better ult.
When you’re playing support, if you have a Juno as a second healer, you know immediately you’re going to have to work to bail out your teammates more. For example, if I’m playing Ana, I know I’m going to have to use my nade to bail my teammates out, and my purp output get reduced, which is honestly a better use of the nade.
And I don’t want to tell my supports to not play Juno. It’d be better if they realize that Juno is a weaker pick compared to other supports and I wish they’d switch at least halfway through the game if we don’t have a dive or some team coordination to take advantage of her kit, but a lot of the times we don’t, and they don’t.
Might as well put out an emergency patch next week buffing Juno since we all know Sombra needs a major nerf (probably a rework). Juno is a weak support but also strangely feels like a weak dps. Her shift is purely for her own survivability, the e skill effect range is kind of doodoo, and her ult range is worse. But players love her, and I get why. She’s super fun, but frustrating to play with during comp.
So I reiterate, please, buff Juno. For the sake of all the Juno mains out there, and everybody on their team.
Edit: This is coming from someone who has played a lot of support and LOVES playing as Juno, but has stopped playing Juno in comp because I know I can choose better heroes to help the team.
