Because Atk will give 3% Assault to everything (Abilities, auto-attacks AND bursts), whileas Ability will give +0.05 modifier to one Ability which has a cooldown AND a damage cap.
Like, Awakened Susanoo first Ability hits a whopping eight times, so damage increase from Ability+ is from 8*0.9 = 7.2 to 8*(0.9+0.05) = 7.6. Cooldown of 5 turns. In 5 turns Awakened Susanoo will hit 6 times (average), so total hit output goes from 13.2 to 13.6 - a 3% damage increase. Is that more than 3% Assault? Probably. You already have a fuckload of Assault from your Grid, so Atk+ is absolutely not 3% more damage (probably closer to 1.5% or even 1%). But we still have to remember that Ability+ doesn't do anything for your bursts, and that this is still assuming that you're not hitting damage cap, which is 88k per hit for Susanoo. Obviously, if you're at the damage cap, then Ability+ will do absolutely nothing for you. Oh, and as a sidenote, I've disregarded Susanoo's third Ability to keep this simpler.
The point is, if Susanoo with her 8 hits is a "probably good" then how good is Ability+ for others? In general, absolute trash. It's the kind of a stat that if you get a Atk+/Ability+ SR or SSR, then you slap it on Ares/Susanoo/Azazel/Brahma, but otherwise, it's just rubbish. Like a SR with Ability+/Gauge is likely to lose to your basic, cheap-as-fuck Atk+ R even for multi-hitters. And once you get better Accessories? You cannot even recycle that Ability+ Accessory due to it being just a complete waste of space for others.
