Gnb is a generic tank. Going off the few job quests and artefact armour I think bodyguard might have been the theme they were going for or maybe squall roleplay if that counts, but I don’t think it’s come across clearly. Maybe this is a product of being added in shadowbringers. Heart of corundum and aurora can be put on a friend, but paladin feels more like one with wings and cover and clemency and veil. I don’t think it particularly works as the described anti-gun troop from bozja either, but they haven’t really done anything to make garlean guns seem all that dangerous in game compared with literally everything else. I think they might have issues conveying theme with the busy burst window they gave it requiring a lot of key-binds, leaving little room for anything else to make it feel unique. It’s in this sort of weird halfway house between drk with busy + gauge management and war with just hit buttons lol.
