I got 20+ kills in a game, went on a 12 kill streak, and still only got my super right before it ended. Besides, our abilities are sort of part of the game, of course we're not happy that they take all day to charge. It's not even a "crutch" ALL supers take forever to charge. Even in the strike I get to use my super twice, maybe 3 times if I'm lucky and take my time.
