That's a real bummer that Warhammer World staff were being so tight with that modelling and painting stuff. I paint my stuff up to a nice standard, but not everyone has the time or patience for that aspect of the hobby.
On the subject of a plastic Thunderhawk, holy Terra. That's some a guaranteed purchase from me once they roll it out (eventually). Glad to hear Sisters are on their way, as I would love to have a force of them for allies.
