That? That right there is why I don't buy any of the arguments regarding visibility. It's a set of different-colored glowing, rotating circles that are thrice as wide as her character model.
On her, yeah. But even then, it's a background effect. I figure out what aura I'm using on her by glancing at my buffbar more than looking at the screen. Maybe that's inefficient or unnecessary or something, but I'd be surprised if I'm the only one.
On the other note, the same argument could be applied to literally any other buff that isn't a shield or heal; at least Sona's auras have a visible sign of their presence in the form of their circles. I'll just list off the top of my head the number of ability-derived buffs (both self-applied and 'giftable') which have nothing but the buff icon on the toolbar (if that): Nidalee's E AS buff, Janna's passive and E AD buffs, Hecarim's passive AD buff, Poppy's passive DR and W AD/Armor buff, Akali's passive spellvamp and damage buffs, Heimerdinger's passive HP regen buff, Darius' E APen buff, Nasus' passive lifesteal, Fiora's W AD buff, Pantheon's E crit chance buff, Olaf's R passive buffs, Sejuani's passive bonus armor and slow reduction, &c. &c.
I don't think passive self-only buffs are fair to include here, because they've been skilled or they haven't; or in some cases, even just exist period or vary by level. Knowing what a Darius' current armor pen is would be handy information, but it'd have to be displayed via six different easily discernible degrees of visual style, and the payoff is similar to knowing if he's carrying a Last Whisper or not. That's not to say displaying character information visually to that degree wouldn't be a noble goal, just that in general it's probably not feasible and in that particular case it's probably not worth it.
Activated ally buffs, on the other hand, are supposed to be temporary or at least situational changes to a champion. Knowing that a Vayne's attacking a lot faster than she's normally able to is useful information; I would argue that attempting to intuitively and immediately convey that information is a noble goal. Situational self buffs are similarly important; knowing Vayne's next attack is a tumble strike is likewise handy to know right now, and lo and behold she crouches while it's active. Knowing that she's faster while chasing you is nice information, and they try, but it's just a little circle- truth be told, you're more likely to notice and remember because she's catching up to you than because she's visibly on the prowl. But in that latter case, she
always works like that, so it's far more forgivable than if Nunu's Bloodboil or her Tumble were represented by nothing but a colored ring and a buff icon.
The game is literally stuffed with passive effects which boost stats, and Sona's auras are actually among the few that do have distinctive non-icon indicators that they exist. Either they didn't give more than a few moments' thought to these changes, or the whole 'clarity' heap of crap is just an excuse. I "remember" that my auras are up as much as I remember my passive boosts on any champion, and unlike most they're also fairly evident if the Sona is a teammate rather than me. The only audience I could see not noticing that they exist is composed solely of new/bad players who don't have and don't seek to develop an understanding of even the most basic aspects of any champion they don't own.
In addition to the above, I'd like to point out that
clarity and
legibility aren't the same things. It's entirely possible to make an effect that is theoretically possible to decipher, but that doesn't mean it's intuitive or easy. "Noticing they exist" is much like "dodging the spear," in that it's one thing to do so under controlled circumstances and another to do so easily and intuitively whenever it's important.
Also, and this point has been raised quite often elsewhere: A triggered shield is not an aura. A single on-hit damage bonus is not an aura. A brief spike in movespeed is not an aura. An aura is a sustained effect which persists, rather than something which briefly exists, triggers an effect, and vanishes. If we're going to be pedantic, it's this:
the distinctive atmosphere or quality that seems to surround and be generated by a person, thing, or place
AKA a permanent or semi-permanent quality.
Yeah, alright. But I've never considered Sona to be "the aura champ" because of the pedantic definition. I've considered her the aura champ because she's a very helpful, supporty support who assists multiple allies at once. For me, at least, running around snuggling everyone isn't going to destroy who she is, because that's still mommying everyone around you just like I want her to be doing.
I get that the particulars of that are going to be subjective, and that not everyone is going to see it that way. But I do have to wonder why passive auras especially would be so critical to the definition of who she is.
Sorry if I'm being a little overbearing here, but it really hurts to see one of my favorite champions (in terms of backstory, character, core mechanics, and playstyle) be disemboweled as part of Riot's current obsession with flashy effects over interesting mechanics. Also, we already have a support/AP caster who can give shields and speed boosts to allies while delivering decent damage and CC. She's called Karma.
I get that you're passionate about it, and I'm
still cheesed off that they destroyed Soraka and Warwick's stories for stupid reasons (MEANWHILE JAX). So I certainly understand the concept, I just disagree on the particulars.
