I really wish we could get an 'actual size' comparison between these three bugbears, the Bugbear Tyrant and the Bugbear Warrior from Legends of Golarian, bwcause it looks like the scale is just all over the place and that's a HUGE turn off for me and one of the reasons I started losing interest in the old D&D miniatures.
I mean, I get that there will be height and build differences among all member of a species, but come on! The Bugbear Warrior was very nearly a large, whereas that Bugbear Flesh Glutton looks to be about the size of a dwarf (or smaller, going by the gallery images) - something I could almost accept for the Bugbear Mystic, a runt who had to turn to magic because he'd never cut it as a brute force fighter, but I expect warrior classes to be more...beefy.
That issue aside, I'm really liking these creature groupings, and if this is a sign of things to come, I can't wait for the next set that's, hopefully, sans townsfolk. A set with clusters of lizardmen, serpentfolk, drow and maybe even a revisiting of the Sea Devils (preferably as some commons this time!) might prompt my first pre-order ever.
