I've said it before, and I'll say it again: Arclock has no survivability, thus making it useless in difficult content. Void has Devour and Overshield Solar has Restoration, Cure, Healing nades, and Well Stasis can freeze everything, nullifying incoming damage, and gain some overshield from shards. Strand has suspend, preventing damage What does Arc really have to offer? You are entirely reliant on healing rift or healing on orb pickup, which as a primary form of sustain is a joke. Blind doesn't do enough to sit on par with freeze and suspend.

I think Bungie's biggest mistake with arc warlock rework is chain lightning changes. It was pretty much the most interesting thing about warlocks in both pve and pvp. But, not only they gave it to other classes, but they made it pretty weak. Should have made chain lightning the main mechanic of arc warlock and build on it, but we didn't get it.

Stormcaller needs buff, Chaos Reach needs buff.

They need to give the subclass more team support, as well as buff Chaos Reach. Solar is a must have because it's the best support subclass in the game. Void is strong because Void overall is the best subclass across all three classes. Arc Warlock only gives their team Rift and Arc Souls. Less healing than the other two and with their burst super taking longer to fully expend than Nova Bomb, but doesn't make that up with damage output. PVE longer burst supers need more damage to make up for the fact that you could've done more damage on a short burst super and use a heavy. Personally I would be interested in looking at the following options. For those that don't like these ideas, remember they're IDEAS. I've noticed people get up in arms for discussing ideas as if Bungie will impement them tomorrow. - Increase PVE Chaos Reach damage; it should Jolt targets that they deal continuous damage to for at least 3 seconds(which could be the form of that extra damage depending on the numbers); would also be a viable Overload Champion counter given that it's meant to be cast more frequently than others[in theory] - While Amplified, Warlock Empowered Rift should make other allies Amplified, and Healing Rift would give a faster rate of health recovery(but not overshield); Warlocks should be able to get back into the fight quickly on Arc, just like Hunters and Titans, so adding these would be minor ways to boost their distinctiveness from the other subclasses and boost their support capabilities

Add Blink as a jump option to all Warlock Subclasses and I'd play something other than Void more.
