Stacy is pretty okay in my book. Underpowered and not very relevant right now, but not unusable. She hurts big time by having an 8 gem spawn and hazarding RNG on which color will actually get chosen if you buff anything with more than one color. I think 9 would be more appropriate, as I said at the time of her nerf from 10 gems to 8 due to people stacking her on defense. Honestly, I think she was overnerfed specifically because of her trait, which decent at the time but has slid way down the curve. Even her old 10 would be pretty risky as it goes now since you either have to target a single color troop or you can’t choose the color. She will never be good to the point of stacking as a meta ever again considering the ease of both shredding barrier and dealing with high life troops (both with the same troop, in fact), the five spawner cast limit softcap before increased misses, and the overall effectiveness of troops when you miss in the current environment compared to when that was a thing. I’d still take her over Borealis in a dragon team 9 times out of 10, if I didn’t have those colors anywhere else, because she can turn unused colors into colors you want and stall.
One important distinction is that a barrier will block status “touch” traits on Unity, but not on Adobe. Both will block “touch” traits if the user has zero attack/entangle, unless they get a critical hit, in which case, both versions will apply the status, and dodging the hit with agile will also dodge the status on both versions. (Note: this does not apply to Psion’s Siphon, which will always activate regardless of skull damage dealt or barrier, unless he has zero attack/entangle, where it will never activate regardless of critical hit). This leads me to believe barrier on Unity reduces an attack’s damage to zero, while on Adobe it simply prevents an attack’s damage from being applied to the target (also evidenced by damage numbers appearing on Adobe, but not Unity, when a barrier is hit). It is difficult to parse out whether or not this is the case for guild wars score calculation, as these tend to go either very right or very wrong, but I do not appear to be losing any significant score by absorbing enough skull hits that might have otherwise killed my front troop with barrier (which would have resulted in a less than 4:1 damage ratio, given equal stats).
