Suppression is a big part of Legion. In a game with limited activations, being able to limit your opponents options is a huge advantage, and a effective strategy. Having a faction that bypasses this game mechanic is a massive blunder. Gaining no cover from suppression on cheap units with 6+ minis is not really much of a disadvantage, and can be compensated by terrain. Ion X is a poor substitute since it is expensive, and costs an action to untap, which pretty much nullifies it's tactical advantage.
I think a rework on how Droid troopers operate should be considered.
