Warlocks are missing the "ark" subsclass Titans have no "solar", and hunters are missing the"void" damage. (I might have those last two mixed up as I love the warlock, too much.) all three of which have space for the missing subclass and if history proves true then the last 3 for all three will end up being the most powerful and will take us up to 32 or 34 or 38 or whatever.
