So, as the title says, would you like faction-specific command token uses? Here are some that I thought: Nomads: reroll 1 dice for hacking Pano: reroll 1 dice for shooting CA: extra order on EI aspect Maybe someone can come up with something more original.
Just as a flat rule or tied to units that need to be present for the effect to be an option ? Precedence exists for the second on evo hacker special rerolls. Seems like an awful lot of extra rules a new player would have to learn if it's just given freely by default. You could do something like make the vanilla factions have stat related rerolls (like in your suggestion) and give sectorial specific and weird uses. I suspect that this might be shot down as 'too games workshoppy' with faction bonuses by the large community. There was some criticism of this sort of design space with the tech bee. Also I guess there's a balance consideration, do you give options that make strengths stronger and more defining but potentially oppressive or so you focus on reducing weaknesses thus reducing potential counterplay. I'm gonna try and think of suggestions and post again...
I like the general idea. One of the neat parts about 40k is they used to do a lot to give factions identity. Every faction has their own special rule that is supposed to add more flavor. Would be a very fun addition especially if they could make them by sectorial. However, it would unfortunately be very difficult to balance. For example, Pano Rerolling one dice for shooting would be cool for most models. Then imagine that on a hospital link. The amount of stacking bonuses is already quite large, now you get a free roll to get past that one off model that can throw out a decent shot back to get around those bonuses. A universal buff can seem pretty minor and in most cases it will but, every so often you get a unit that really takes to the extreme what you have set in place.
At first I was thinking "Hell no", but after considering it a while I am more of a "Nope nope nope, hell nope". This is picking the second worst trait of the old Warhammer 40k game design system (the worst being explaining randomness away with "cinematic" and the third worst being Wolfy McWolfson naming conventions, for reference.). What makes Infinity great is the similarity between the factions and the identity in the small differences that emerge as vast differences. It's an elegance that sticking down a sign that says "THIS IS THE HACKING FACTION" sort of spoils. That said, an extra order on Aspect is... significantly stronger than re-rolling a BS Attack dice for Ariadna - if we ignore that re-rolling BS Attacks is blatantly a Pan-O ability. Plus, with that sort of thinking Yu Jing will end up with a shitty re-roll of a CC Attack dice, which is useful in all of maybe once per tournament.
I think it would be more interesting to have new uses tied to specific units rather than factions, and far easier to balance.
