It's silly that a class would go "Hmm I need to get across that gap but I can't because I'm a hunter and I'm not allowed to glide or Lift to get there!" There are enough differences between armor and class items, class abilities, melee abilities, and Supers. If anything, each class having access to Lift, Glide, and Double Jump would make the game more fun and create new playstyles and I cant think of a single class or super that would be broken with access to all three...maybe. Hunters would never be traumatized by platforming sections ever again. Warlocks would never have to break their necks trying to look up against pogo hoppers in PvP and Titans could accelerate into and out of a Shoulder Charge ability with Burst Glide and during Fist of Havok, this especially would make the Titan community very happy and yes, this is the kind of terrible idea Destiny 2 needs right now. Edit: Blink is out of the question for obvious reasons.
