How do you unlock those abilities?
Hunter is just a lot easier to move in close up fights in pvp. I've seen Warlocks move quick but they're using that dash which is why I wanted to unlock it for pvp.
They added so much shyt to this game as far as how you build your character since I played it in Destiny 1. I don't feel like reading a fukking manual
The only subclass that requires you unlocking anything at this point is stasis. Every other subclass is fully unlocked - and anything not immediately available in the menu can be bought from Ikora straight up at the tower.
And yeah - its a lot these days
the movement you're seeing from warlocks is *probably* just the warlock skating shyt where you build momentum, jump, then have your mousewheel do all the shenanigans necessary while you pick and choose when to cancel out of it.
You can do additional stuff with glaives, swords, and other items. But Icarus Dash is a solar/dawnblade function and has crazy value because you can shift momentum even better than Twilight Garrison titans from way back.
I got 4k hours in Destiny between 1 and 2 and play more PVP than most. I can try to steer you in the right direction more or less.... but Hunter is generally a good starting point for any player in this game considering its gonna be the most familiar to anyone who's used to FPS games.
