This is something that I thought the other day: What if they introduced a new damage deck that was split in 3 colors: red, blue, black. Each color corresponds to the die color that made the crit/damage (2 blue hits, 1 red hit + 1 red crit = 2 facedown blues, 1 face down red and 1 face up red) and this way you could bring new life to crit effects, especially for blue die.
Blue crits could be devastating stuff, like shut down engines, weapons failure, etc, making them a much bigger threat than they currently are (and fitting lore-wise to the "ion cannon" part of their nature), while black crits could have a higher chance of giving structural damage and whatnot.
Or, how about a standard, face down deck, and colored face-ups decks?
Anyway, like mentionned in the title, food for thought!
