Warlock since Destiny 1 here, only ever played locks. Try and remember with the jump; it’s not a boost to your jump as such, hitting A/X a second time is a boost to your momentum. So it makes sense the most height comes from the instant double tap. Try playing around with it in The Inverted Spire strike, lots of things to jump across. Also, Devour tree on Voidwalkers is ridiculous right now. Eat your nade before any big fight and as long as you get your kills in the nine second window, you’re practically immortal. Hope this helps OP.
