Is this a bug or just something that's intentional? I find that whenever I have a charged melee and I go to attack with the grapple punch, I instead just throw the dart or the needle. I can only do the grapple melee if my melee charge is completely empty. This does not happen on the Titan as I always do the grapple melee over the regular melee regardless if my charged melee is up or not. The only fix I seemed to have found for the time being is to bind my charged and uncharged melee to completely different buttons. I wish the grapple melee would prioritize the unique melee over the regular class melee.
