For Thunder maybe it was yes she's a niche unit with slightly unneeded buffs on her... Well, let's look on the bright side as well, she's the first double BB Attacker that was way too high even for her standard.

For Water, the Spark Buffs is also working same as Silvie if you look it closely, the comparison is that he can't do double BB ATK but at the same time he got lots of Offensive buffs on his side to be used rather than Silvie in terms of shared. In the end of the day, both of them got same or slightly better to Zelest in the matter of BB Damage Modifier because he got Breaking ATK Cap in damage capability. Just see, first of all, Zelest is the combination of Status + Critical + Sparker as his main selling point while Silvie is Status + Sparker + BB Gauge Management, as you can see it's not that far away from what I tried to compare to. Silvie can boost Status same as he did with him only lacking REC Boost and that buffs don't need any Enhancements at all... Even though the downside of it is that he can't Self Boost his own Status unlike Silvie which she can but downside of her being selfish is that she can only boost Status, Boost BB Gauge and AI that doesn't really unreliable at all while Zelest is in here can do more in terms in defensive and attack. With buffs like Melord that can cut ATK and Boost ATK relatives to DEF, we can sure this unit packing more sharing buffs than Silvie and practically more reliable than Silvie in attacking system. Her SBB can do double attack but the downside of it is just making her another Sparker with selfish buffs with 2 buff that can be shared and that's not even that cool if we look it up again. Silvie Spark base without enhancements is 120% while Zelest is 130%, the enhancements for another boost to be 150% is also favored to Zelest rather than Silvie if you want to compare it again because he has cheaper SP cost than Silvie. The another downside of him being not a double BB's attacker is that he can't self Spark boost which Silvie can but that's covered up by Critical matters. True that Critical wasn't that much useful in terms of usefulness but hey, at least we got Spark on him too so it's basically a good alternative Avant or even better with lacking BB ATK Boost, the good news is it was shared unlike Silvie.
