Their redundancy with Lighter is non-zero but it's very minor.
>Eve
Mechanics and multipliers
>Astra
More mechanics + ATK stat stick
>Lighter
Daze acceleration + stun extension + DMG% stat stick
There's overlap with
>Nocturne and Lighter scaling Fire RES% Shred
but the saturation is minimal at that stage
>Laurel, Summit, Nocturne, and Astra all scaling CRIT DMG%
but I'd argue neither of the sources other than Nocturne completely all-ins on the bonus, so you're mostly looking at a distributed saturation there
>Lighter, Astra, and Astral all scaling DMG%
Which is, again, mostly comes from one source (Lighter) with the remaining sources providing a mostly distributed saturation.
You'd need a very specific kit to replace Lighter there without outright powercreeping him in the raw stat department, when he's already incredibly high up there due to being a specialist.
Like, just Lighter's maxed AA is 50% more raw stats compared to Fufu's maxed out Core.
Most stats are saturated very evenly, which is why that team is so strong.
Compare it to, say, S11 using The Brimstone instead of Eve:
>The Brimstone is literally a bigger ATK stat stick than Astra's buff, so it's insanely saturated
>Her BAs start at 80% DMG and are usually scaled up to around 100~120%, meaning for around 30~40% of her outgoing damage total, Lighter's primary buff is also incredibly saturated
I'd argue very few teams are as synergistic as Eve/Lighter/Astra.
