You can blame FFG for that, they use stupidly thick bases that I initially hated, but once you have a completed force with sand and grass tufts out on the tabletop it's not too bad, I've updated my feelings from "hated" to "miffed". I actually dislike the bases Legion uses more than I dislike the the movement widgets or custom dice or slightly larger scale, I wish FFG had used standard 25mm/40mm etc bases instead of proprietary ones.
Cracking paintjobs as always, however. I'm slowly transferring my SW collection from WotC/IA to Legion, slowly enough that I haven't bought any of the any aftermarket figs yet, but it's nice to know how well they paint up if I ever do
