I think giving us a "Darkside" subclass would have been a better story, to me. The guardians end up going to the Darkness for help. Maybe end up making guardians "grey" controlling both light and dark. Rolling around with an "evil" Titan laying waste to enemies would have been awesome.

Just don't use your abilities and don't double jump. Bungie probably won't add it in so this is as close as you'd get

Except you can only normal jump so you can't get anywhere in the game lol
