Jade is definitely an upgrade for Blade. He will do his FUAs twice as often. If you are a Blade main then go for it. Using both Bronya and Jade together is also great.
Definitely possible. The stats requirement will be higher for your DPS characters. With the 40% Def reduction from my support's Eidolons; I am doing about 26.5% more damage. Your DPS characters will need to compensate that in stats. Having Blade being E1 will make it a bit easier since he will do more damage with his ULT.
Is jade worth it over having bronya instead
