Of course, the Riftforged Orcs have more than the new plastic kit. There are some cool new resin models as well.
One of the new heroes is the Stormcaller, the riftforged version of a godspeaker. Of course you have the option to take it mounted - but instead of a gore it comes on a Manticore!
The model comes on six spruelettes
The body of the Manticore, which, unfortunately, has the Stormcaller legs and torso molded onto it (somewhat limiting the re-use for other heroes - though that is more from the torso than the legs, as the legs would probably be reusable).
