No, don't do that. It doesn't make any sense in the lore, and we shouldn't be restricting players from skill lines.
I would debate you on the lore and how herc grants healing powers while mb does not or how aligning with any of these daedric princes would, by lore, cause the gods to likely retract their powers from said mortal (as has been done in game's past from NPC's). But I digress and don't really care as much about the lore as I do with playing a game that implements strat and diversity which is not something Vampire Scrolls Online is doing right now.
