I'm completely ignorant of modelling so I find these these small variations packs very helpfull, especially to make sure there is consistency with the base models of Warcraft 3.
One thing I would like is to get rid of the stupid pandaren face on Illidan's blades if that's doable. This really was the worst place for an easter egg by the warcraft team.
Also, there is a pit lord model in the screenshots, but he doesn't seem to be in the pack yet.
