They woul still get augment slots on earpieces. 1.2 did add that all items that coudln't get an augment would provide double on a crit.
Yeah, you're right. Somehow earpieces had completely slipped my mind. (which is odd, since they're probably the most profitable item my cybertech sells right now)
Curiously, ship parts (and speeders) don't get an extra when they crit, and I'd argue they should. It's all percentages anyways. Critting 15% on a mod that takes 8 mats (or w/e) vs critting 15% on a spaceship 9that takes 35 or whatever) is still giving you the same % of extra "free" mats over the long haul.
