I think every class then the ONE Class should have Unbreakable. Not the Titan one... Titan is void. Warlock should be a solar shield that grants Restoration x2 when up and popping it grants Cure x2 in an AoE. No resist on the Warlock version. Hunters should be arc flavored that grants a passive arc conductor effect and then after popping grants Amplify in an AoE. Resist .45 which is half of Void Unbreakable at .9. On Solar Warlock Arc Hunter Void & Prismatic Titan as aspects. @Bungie... for your consideration, please and thank you. 😇👍💠
