[@Andreyich]I, for one, would be really excited to see someone do an Ultramarine. Ever since the schism in the fanbase over Ward's writing, hardly any fans have wanted to write anything serious involving them for fear of backlash, and as a general 40k fan this has made me sad, because there's a lot of things that can be done with them. So in my opinion, it'd be nice to see the Ultramarines used again.
