I am not sure if in a whole europe but in my country, woman body is not a big issue. Her Thor cosplay is one of her best costumes so far, so i dont have a problem when it is used in a promotional stuff together with her name.
What i dont dig is a breast plate of her Warlock version. With little imagination, i can tell now, where are all those demons are stored and came from
But if this kind of approach will lure players from a customer segment which would normally didnt know or even play MW, it is a good choice from a perspective of a marketeer/promoter.
Of course, that there is a limit. If the next step would be SM Necromancer female version made of shiny things and leather, that could cause an actual trouble. (despite the fact, that this will increase sales in germany
)
