Well bungie isn't willing to redo the whole sunsinger class. But including that one I'd say 3 need looking into. Blade dancers, sunbreakers, and sunsingers. The changes made to storm caller I'm content with and it shouldn't be messed with further. Void walker is also good. But I'd personally like to see embrace the void trigger your other melee perks. Not just the intrinsic one. Striker is perfect. Same with defender. Night stalker needs a fix on the shade step exploit. I'd like predator and courage to up updated to be useful. But honestly the class is fine without that. I'm on the fence about gunslinger. It's basically perfect. But I'd like the flame knife to get a buff so it can actually kill someone with the burn. And I think it's damage should be bumped up slightly for pvp so the only thing living from a shot is a max armored Titan mod fist of havoc. I'd also like the nerf on the symbiote to be reversed. But yeah overall the classes are in a good place aside from 3. Otherwise just some minor preferential tweaks.
