Melee ability needs a separate keybind for real. I'm sure every subclass could use it. Lack of buttons on consoles is not an excuse, as there are enough button combinations to add one more keybind to the game. For me, Behemoth's melee is ruining my day as I accidentally use it and find myself falling off a cliff suddenly. If this is not added to the game soon, I'll do another feedback post about this in the future, and I'll keep at it until this is implemented, unless, that is, I quit the game before that.
