I see it the other way around, they are part of a design that blizzard came up with in order to prevent those hybrids from needing to weapon swap to be effective. Even in pvp I find myself using weapon swaps to heal up.
Weapon swapping to tranq even right now is quite annoying
I would call feral weapon swaps being more beneficial than using an agi weapon when we have nurturing instincts "poor design"
