I'm right there with you. Sup Dice are the Battle Master's thing. I'm glad they stopped handing it out to every new Fighter. It'd be like handing out the Champion's expanded crit range to a Warlock at 1st-level...oh, wait.
DISCLAIMER: I do love the Hexblade as a patron option, as I'm sure everyone's noticed, but that one aspect bothers me a lot. And Hexblade's Curse should totally apply only to melee weapon attacks.
