The additional melee charge does not work on the Defender subclass. Even though I have the bar below my melee indicating I should have two, one punch uses both of those charges. Am I missing something? Or is it just not working? Making it even LONGER to get my void ability kills for my Dark Drinker :( mistake to do it on my Titan in the first place! But I'm trying to get every help I can! Works fine on both Striker and Sunbreaker subclasses.
