I never noticed that thing with Chewie in ROTJ either, and I'm a pretty picky guy. Cool...
The stormies in ANH do get a lot of hits at the beginning of the film, and I think we in some way respect them for that. But as for ESB, I don't think a single stormtrooper hit a single target... and that pretty much sucks. That's why I suggested, along with this change, that we have snowtroopers on Hoth take out a few rebels after Vader lands, in close-quarters style combat.
BTW great job on the Roque 3 change. Never noticed that either.
