You are objectively wrong arc has innate DR via amplified, as well as a way to heal via knockout on titans and combination blow on hunters, and both of which not only heal but also provide additional buffs, more so than other subclasses healing then warlocks have rift, which can be supplemented by arc soul, the only classes with no innate healing outside of warlocks rift is stasis titan and hunter, and strand hunters, but both of those don't need innate healing due to the super heavy CC nature of them

It does with tablet of ruin. Dielectric and defibrillating blast both heal based off of Arc play with tablet of ruin. I guess if you mean baked into arc at its base it doesn’t, but the aforementioned artifact perks work well. I’ve been using arc titan with bitter end (trickle charge/jolting feedback) and Trendsetter (trickle charge/gear shift) and the healing is plentiful.

[quote]It’s sad that Arc will forever remain the only incomplete subclass, as I believe it’s the only one with no way to heal and/or protect ourselves. Such a great subclass left unfinished like this feels almost sacrilegious.[/quote] I mean Bungie made it pretty clear when Arc 3.0 was released that it was more of an offensive subclass rather than a defensive one. Regardless, there are plenty of ways to heal and provide DR through mods, fragments, and aspects. Titans have Knockout and Hunters have Combination Blow which both provide healing and can be further enhanced through exotics. Warlocks lose out the most but still have a Rift and can also use something like Karnstein. That’s not even factoring in the artifacts we have access to now. Arc is still one of the most potent classes across the board and if you know how to build it properly then it has perfectly fine survivability.

Doesn’t Arc Warlock have a rift that can heal ?
