The more you feed the more human you look, whereas if you don't feed your powers grow stronger and you apparently look more like a vampire, making it harder for you to blend in amongst the "herd". That's the reasoning anyways. I Don't really see a downside besides more vulnerability to fire and vulnerability to sunlight. Both of which can be avoided. It used to be you'd get attacked on sight by npc's if you got to stage 4 but that's no longer an issue with the dlc enabled.
Honestly I wish their were stronger blood magic, like a stronger vampiric drain, which does get stronger and caps at 5 life per second at stage 4, which is still really weak considering flames does like 8 dps baseline, frostbite does 12 with the perks. Sure you can make it drain stamina and magicka as well if you use the blood chalice, but still it's overall weaker especially considering npc vampires drain does up to 20 health per second i think it caps at, if not just baseline. There's no progression there it's just the novice skill and you can't get better versions.
It's also a bit disappointing you can't kill enemies by feeding on them unless you get lucky with a power attack in VL form...
But yeah, no real downside to speak of, I just stay at stage 4 as long as i can, i get sad if I'm forced back to stage 1.
