Okay, so I know I should probably wait and see before I judge, but I'm already preparing myself not to like the new Rök model. I think the generic plastic dire troll sculpt looks fairly weak, and I think Rök sounds too cool not to be unique.

I'm guessing it won't be tournament playable, but hopefully it will look better -- though I think I'm going to omit the Santa hat, Greg. If anyone has any alternate thoughts or suggestions on how to do the modeling (which I suck at), let me know.
I think that a Khador jack axe would be more appropriate. You could just model some scraps and rags on the handle and chip/wear down the blade a bit.
I think that Dire Trolls are becoming pretty swappable honestly. The classic Dire Troll Mauler looks NOTHING like the new one, so I think conversions should now be much more open for dire trolls.
