I have the core Imperial Assault box, unopend and not used. I have looked at the miniautures when I bought it, at the time I planeed to use the miniatures for a homebrew Star Wars miniatures game, but never got around to it. The, a few weeks, late to the show, I got in to Legions, and I love it. I have been buying what ever I can get my hands on for the four factions (yeah, I started out with Imperials, but now have all four of them).
Size wise, if not in a true miniature game, I would say that they dont really fit. But, i dont have the droids from IA, only the core set (whitch I plan to sell), but I will check the IA droids out, any suggestions to what expansions I should look for would be most welcome, I want them for general flavour as terrain features.
I get that most of the people that bought a lot of IA stuff are a bit disapointed, so was I, but then, the stuff that FFG are realeasing now is so great and berautiful I dont mind.
I did however buy the crew from Rebels, and I dont care if there is a slight size difference, I want to have them as proxy troops or heroes for Legion!
