Honestly, if GW isn't going to give us any new named characters they just need to bring back some of the old ones (no pun intended, lol!).
We really need named characters that can actually hit hard while being hard to remove from the battlefield, especially since they seem determined to keep all of our dinosaurs as glass cannons. It would also go a long way to add more flavor to our faction and tie us in to the lore of the actual setting better.
They left it open in the End Times stuff that characters like Kroq-Gar, Tehenahuin, Gor-Rok, etc., could very easily have survived by getting onto the temple-ships when they were taking off. And since at the very least the Saurus are biologically immortal, they could still be around. They could just come up with some magical stasis handwave to explain how Skink characters stayed alive this whole time. Maybe they're all immortal now with the whole star magic infusion thing going on, who knows?
