I have used her. under virtually every circumstance for the past 3 months I'm better off using spica + bashira. she's only good if you dont have bashira. and even then under most situations I'd rather deploy spica or soma (because I didnt level/aff my daniela after CC). also, traps are nice and all, but you can pretty much do the same with necromancer tokens, which apparently are arguably better. she's simply too niche, and cannot completely replace bashira in videos and her cost is much higher than daniela.
seorizuki has a fair point, but even then most of the time you can just use an archer and manage somehow because snowstorm isn't forever.
