Holy ****! What a difference a paint job makes... I just realized that the ARC's rifle is the exact same one as the rifle that came with the Clone Wars ARC in 2003. I thought it was different the whole time.
I also opened the other two packs today:
Luke/R2 is a good set. Luke is about the same as Han, and I like how they added a "rusty" paintjob to the E-11.R2 is really cool, and like Chewie in the Han pack, can be used as a completely different astromech. My one complaint is that Hasbro used ****** bendy plastic for R2's legs, so it's more like a repaint of the astromechs from the Final 22, not R4-G9 (who had strong plastic used in his legs).
Vilmarh/Vos... cool set overall. The lack of leg articulation sucks, but everything else about them is cool. When I first saw the prototypes, I thought they looked too skinny and the sculpts looked bad but in person everything is much better. Vos and Villie are quickly becoming two of my favorite figures.
Overall I'd say that every set in this wave is a winner. If you passed on Wave 1, do yourself a favor and at least pick up the ARC/Obi and Vos/Villie packs.
