The Legion of Everblight kits look pretty good, but the Trollbloods and Circle Orboros ones really sacrifice the individuality of the Pureblood, Mauler and Blitzer models to make the kit. I don't mind it, but I won't be trading my Mauler anytime soon, and I might pick up a Blitzer if I ever need two.
For those who don't know, the characters in Hordes Domination will be upgrade kits on top of these multi-kits, making the new characters cost about $50.
