Actually they aren't. There's about 8 different "super" classes. Each one is distinctly different. I'm pretty sure Destiny doesn't have a subclass that shots 15 grenades from a grenade launcher? Or how about a super that becomes a shotgun that shoots ohk balls of electricity? Seriously, take off your tin foil hat.

^cod fan boy alert! You cant even properly use the term "tin foil hat" so GOH.

Lol Your mother should have swallowed, or better yet, aborted you. Giving you a small glimpse at life only to have you sucked out through a straw. Anyways, you should move along kid because you seriously lack any skill at trolling.
