Lamae bloodline is a weak strain to balance the game. Lore wise Lord Harkon was a demi-god. Would be to powerful ingame but again I believe your overall strength and skill transfers to Vampire Lord form as some are unkillable unless Aedric gods or whatever kill them. Werewolf tanks are immortal in non-CP basically and a pain, I know because its my PS4 Main ( Best version of the game by far ). They should add Vampire Lord form as it already exists ingame on thew vampire Lord quests which will sometimes turn into gargoyle form type. They should add it to vampires in spell crafting or change one of the batswarm morphs to gargoyle. Literally just add same 10k resists buff like werewolf and call it a day. Good enough for me in my view. Also bloodfiend permanent pet\ friend or lover who could not fully transform and or handle it become almost pure instinctual but listen and remember you. A tragic yet beautiful relationship. Your bloodfiends humanity is left in you the vampire and you care for the bloodfiend in that it reminds you of the humanity you once had and show mercy to it and it still cares about you. Anyway just like warden has with bear ulti it could be another option. Serana is entombed of course but Lord Harkon is in Western Skyrim and very well may appear in ESO and even offer Vampire Lord form to the player. Also will clarify Lamae was\is not weak but just is weak compared to vampire lords. She was the first but just a toy, bored molag bal ***. Unfortunate but true and was also not given pureblood Vampirism. Sorry off topic just people seem to think Lamae bloodline is strong and will say yes we can survive in sunlight without burning and getting injured much but the sacrifice is huge power decrease lore wise .
