Lucio’s biggest issue is general powercreep. I’ve had people try to explain to me on these very forums that the concept of powercreep does not exist in Overwatch, which is laughable.
Lucio’s usefulness is just completely outclassed by other options. He is a riskier and more difficult hero to play than some of the other supports, but offers minimal rewards for that risk. Unlike Mercy, who is low risk and high reward.
That, on top of Lucio’s ult being near useless in the current state of the game (not meta, but the general game as it stands), and Lucio’s healing being negligible -and yes, I understand Lucio’s primary role is not healing, but when other heros heal more but still provide more and better utility, why have a Lucio?
Lucio’s Sounwave is also an ability that desperetly needs looking at; since the Global Movement update it feels like a practically useless ability, and now every single hero that comes out has a mobility to just straight up negate its effects.
Most importantly is that Brigitte has come out, which originally worried Lucio mains; her kit sounded so similar…but I feel like the devs anticipated the anxiety and took pains to explain that while they sound alike, they’re actually different…but then Brigitte actually was released, and sure, they’re different in that most of her kit is flat better. Her survilibility is better, her damage is often better when paired with her kit, her self-heal is better, her overall HPS is better, her ult feels better to use, and her Chain Whip ability is almost insultingly better than Lucio’s Soundwave. The same CD, but 20m range, and more than double the damage (25 to 70), and a far stronger, more consistent knockback.
Almost every major patch that has gone out for more than 6 months has included some form of indirect (unintended) nerf to Lucio, but nothing has been done to counter this. This, on top of heros like Mercy, Brigitte and Moira just being too dominant right now, has absolutely decimated Lucio.
I think Lucio desperately needs a small buff. I think the state of the supports would be fixed if Mercy got moderate nerfs (rez should be behind an ult for sure, but big-rez should not come back), Brigitte got toned down, Zen’s discord could perhaps do with a tiny bit of toning down, Ana could use a tiny boost up, and Lucio could use some dusting off.
My suggestions for Lucio would be that his healing heals based on a percent of the targets health rather than flat healing. So he can heal big-guys up a little more easily. I don’t think the radius needs adjusting. Lucio’s ult needs to be buffed a little; the cast time on it is ridiculous, the charge rate for his ult is laughably almost the slowest in the game, and its effects are practically useless in the game with the current cast. More shields, or more lasting shields, or something like that.
Lucio’s soundwave also needs to have improved knockback. It just needs to feel slightly more consistent, and have the knockback range increased a smidge. Those are the changes I feel are most important.
I’d like for Lucio’s projectiles to go a little faster, but I don’t think he absolutely needs that in the same way he needs the other changes.
