I've played the strike a fair number of times on all three characters and I seldom felt the need to use my super. In fact we've nearly beat it a couple times before I even got my super, or so it seemed. Granted, it was due to the fact I didn't want to use it until I felt it was an absolute necessity. However, I'm also well aware that mindset can be dangerous and lead some to hang on to their super when in fact it would've benefited the team as a whole to use it.
