I love this game. I threw together a couple decks in no time flat (not my best work, but they function)., and am looking forward to tweaking them, especially when the force packs start hitting.
I don't understand what the problem is with distinguishing between the tokens…
Color similarities or not, how can you mistake a grey octagon with a red 1 or 3 (which are larger than the focus tokens, too), for a small circle with a red crosshair? The shapes alone should be distinguishable enough, even without the fact that the design on the focus tokens matches the tactics icon almost perfectly, while the damage provides numbers for easy quick reference.
When I'm consciously thinking about the differences between them, it's obvious. But during play I prefer to have my thoughts on what my opponent is doing, and how I will respond. When there gets to be a pile of tokens that fall in the same region of the visible spectrum, in two varieties that have nothing to do with each other, I instead have to make the same conscious consideration that I do outside of play, and this would not happen for me if the focus tokens occupied a different area of the spectrum. I know this because I have not once mistaken a shield token for a damage token, but have done so several times in the case of focus tokens versus damage tokens. Again, my attention has to be focused (pun not intended) on the tokens in order to reliably add or remove the right kind, and I don't like this.
