I like that she has this messed up love life tht she is pretty unrepentant about.
As for Dr. Druid...he got screwed man.
Doc Druid should be Frazier Crain with powers, an genial, but arrogant snob who tend to drone on about his latest novel.
I see him commandeering Jarvis kitchen on occasion to serve the Avengers a "real" gourmet meal. I see Druid and Jarvis as buds, Jarvis being the Niles to Druid's Sheffield.
Dr. Druid's classic power set actually works even better for the Avengers than Dr. Strange' s becuse he is not a Deus ex machina. Yes he can do everything Dr. Strange but only if he has a spell book/scroll to read it from.
Dr. Druid is only really tough in his library. Outside of it, he's only a garden variety telepath/telekenetic.
Dr. Strange only works for me as a Defender. To me the Defenders are Team Overkill, the scariest dudes (and chicks) on the planet. That they have even gathered togeter in the same room means that things have seriously gone to hell. I don't see the Defenders as impinging on the Avengers brand or anything like that.
The Defenders don't get out of bed for anything less than the rising of Chthulu and crawling, nameless horrors of that general sort.
