I felt like such a noob when it took a fellow raider to point out to me that the warlock glide can be turned off and on by follow-up jump button presses. Absolutely changed the game for me and made glide viable for me in pvp. But yeah, something that simple was not clear to me from the beginning. Maybe it would be highly beneficial to add in some more class specific missions. Given by each respective vanguard class representative. It could be a series of short tutorial like missions that help teach you the ins and outs, advantages and disadvantages of your class abilities. They would only unlock once you have actually unlocked that skill. The opening mission is a tutorial for general game mechanics, but nothing class specific. I would love some maze like platforming mission where you have to use your jump ability in specific ways. Or you're stripped of weapons and can only use grenades or your super. Something to practice on before you hit the raid.
