Out of the six players at my table each week, two are utterly dependent on d12s for their weapon dice. (And because two don't use weapons, that's half of the weapon-users.) d12's get a LOT of love in 4e.But the question is, which die type is the most marginalized? Is it the d8 or the d12 or maybe the d4?
I'm voting for the d12--it doesn't get enough love, especially since the days of S-M/L weapon damage.
If there's an unloved die in 4e, it's the d4. Unless you're a rogue, you probably don't use them.
