Instead of four Boss Blinds that debuff 1 suit each, there would be just 1 Boss Blind, which debuffs your most common Suit at the beginning of the Ante (ties chosen randomly). This opens 3 slots for new Boss Blind ideas, and doesn't really affect anything else. In either case, there's just the 1 boss blind that will kill you (if you're building to a specific suit), but now Wild Cards don't get debuffed by four different Boss Blinds.
This does nerf builds that rely on individual suits, as the other 3 suit bosses would typically not hurt them very much if at all, but now might, but I think that's an okay concession to make.
