I've been playing with ZOS's vampire rework since its early days on the PTS server, and while I never agreed with anything ZOS came up with for it due to its lore breaking nature I continued to stick with it. Sometimes I'd cure my character but I kept going back for roleplay reasons and this nagging desire to see just how far I could push the spell damage buffs vampire gave. Over and over I tried to make the new vampire skill line work and failed.... until Markarth gave us the Ring of the Pale Order and now I see what was has holding ZOS's vampire back.
First we have to look back at that video in which the creative director said "Blood Frenzy ticks all the boxes of what it means to be a vampire." I'll link it for those who have not seen it.

When I first heard that sentence I honestly felt like ZOS had lost their mind since nowhere in Elder Scrolls lore do you see vampire sacrificing their own vitality for power. Its always been about siphoning life from other people to fuel their abilities. ZOS originally intended Vampiric Drain to be that ability that gave you the vitality you needed to fuel Blood Frenzy but due to just how terrible of a healing ability it is nobody in their right mind would use it. With the Ring of the Pale Order I've found myself suddenly with more health than I can use, which led to me slotting Blood Frenzy and
still having more health than I can use. That's when it hit me as to what Rich was saying about Blood Frenzy. He intended vampires to siphon health from their foes to fuel their frenzy ability to grow in power.
Here are a few things ZOS could do to make the vampire skill line fit better into their game and fulfill what they originally intended to do.
First off making it so other people cannot heal you with Blood for Blood and Blood Frenzy active is honestly a really bad idea. Both of them together? Sure I can see that, but to make that a reality both abilities should limit incoming healing by 50%, and that 50% can stack making it a true 100% when both abilities are in use. That would be balanced and make vampire DPS a little bit more usable in groups, while also making the Blood Frenzy and Blood for Blood combination a bad idea as it truly would lock them out of group healing completely.
Buff Vampiric Drain so that its heal is based off max offensive stats (Maybe even make it scale off your highest offensive stats for stamina Vamps) or max health instead of missing health like it is now. Vampiric Drain seriously needs this buff as the heal is so weak that Sated Fury is actually a better heal than this ability... and every other offensive ability in this game that comes with a heal, not only to mention its channeled and has so many counters it should really heal more. (Burning Embers, Bloodthirsty, and Swallow Soul to name a few better offensive heals.) In order for Vampire to truly feel like a vampire it needs far, FAR more healing to fuel its abilities. Vampire is currently all health sinks with nothing to really fill the pool back up.
Last thing is the lack of mobility vampire has as its a melee focused skill line with no way to keep up with its targets. I could rail against the stun being bad but the fix is honestly a bit more simple than that. Vampire used to have Minor Expedition on Accelerating Drain which was an old Vampiric Drain morph before Greymoor, and the ultimate called Clouding Swarm had a gap closer built in. Some on the forums have been begging for the gap closer, but if ZOS introduced the Minor Expedition buff onto the stage 4 passive it'd honestly be a life saver.
TL;DR: Vampire needs a bit more healing in the skill line so that it can actually take better advantage of some of its abilities, also it needs a small speed boost to go hand in hand with its melee nature and lack of a gap closer ability.
