One FFG developer specifically said that pass rule was instituted not only to balance out the 4x4 issue, but also give more value to unique figures. They also said that Return to Hoth was the best that Imperial Assault can be. That, for one, has me very excited. But I'm also wondering if there will be some command cards/skirmish upgrades included that can only be played on a unique figure?
Personally, I hate errata or nerfs in games. I think it's better to prop up what is weaker instead of weaken what is stronger.
