Dark plumes?!

Olanden

So - whats the take on thise Dark plumes. I have Phoenix already but to awaken her seems so far out. Need to buy some serious amount Of Daily offers. At a Price that equals light essense to Get luminatrix. But he ‘only’ cost 12 light essence whereas it cost 75 !!! I see no one talk about This in the forums. Have i misunderstood something or people have given up on her?
