Dawnblade with none of the Dawnblade assisting perks (Top tree's Icarus dash or bottom Tree's Fated for the Flame) is kind of hot garbage. You sling fire and it doesn't home, you have no melee option (the super is casting fire from a sword but I guess Warlocks aren't quite big-brain enough to use it as just a sword), and you have to jump up into the air to use it effectively. Base Dawnblade on it's own is really not a good super. Sentinel Shield is at least a functional super without the associated perks. Shield Throw is inconsistent af, but the melee game is pretty good, and you can block incoming damage.
