I'd rather see new subclasses. I once created three "traitor" subclasses, where you get new abilities by aiding enemy races, though not against fellow Guardians. Hunters learned from the stealthy and ingenious Fallen, Warlocks studied the reality-bending abilities of the Vex, and Titans were educated by the Cabal.

Yeah I know a new class it's called a ummm [spoiler]huntlock[/spoiler] It's a new breed of hunter and warlocks You can self res and the bladedance everyone You can shoot a Nova bomb that golden guns everyone near it. You can be a stormcaller with a new type of wombo combo and when you start it, it invariably surpasses 3 randomly chosen people. #makethisarealthing
