I played Sisters of Battle for years. I've grown immune to identical poses, because no way in **** was I going to convert an entire army of pewter.
I might head swap the leaders on the rebel troopers, and I might tweak some poses on the Stormtroopers. But probably only as I get more units. Like, if I ever build towards the Grand Army level. Three or four sets of duplicates per army isn't heinous for me.
