This seems poorly designed and it tends to swing games. Important, powerful figures tend to be the ones that have a white die, and it punishes lists figures/lists that make fewer big swings instead of multiple smaller swings.
I'm fine with C-3PO and R2-D2 and officers having them, they're just support units, whatever. But when you get a decent roll against Bossk and he X-Mans and then he activates and drops 8 hits into you that's kind of a load of ****.
I understand what they were going for, have weaker white dice that can occasionally spike and dodge everything, and more consistent black dice that block always block something. But couldn't the X-Man have been a quad block and a surge cancel or something? Something that's still very strong defensively but can be punched through?
When I play this game, I've started referring to white dice as "one out of sixes" or "one out of threes" if I have cower or R2-D2's lucky ability.
