I was reading the patch notes and it seems like the changes being made to Vampires will make them more popular. Most notably not having to keep an ability slotted for the recovery anymore.
Vampire
Dark Stalker: This passive ability now only functions when you are in Vampire Stage 4. Fixed an issue where this passive’s Movement Speed bonus while in crouch was not applying reliably. Updated the tooltip of this passive to better describe its bonuses.
Drain Essence: This ability and its morphs now tick 3 times over their channel durations, down from 4, but their damage per tick has been increased and they now restore 20% of your missing health per tick to compensate.
Mist Form: This ability and its morphs now remove previously applied snares and immobilizations, in addition to making you immune to any new ones while active. Increased the cost of this ability and its morphs by approximately 5%. Updated the tooltip for this ability and its morphs to indicate it has always disabled your Magicka Recovery while active.
Poison Mist (Mist Form morph): Renamed this morph to Baleful Mist. In addition to the changes made to the base ability, this morph now ticks and deals damage every second instead of every 1.5 seconds, causing it to deal damage 1 additional time over its duration. This morph now deals Magic Damage instead of Poison Damage.
Supernatural Recovery: This passive ability no longer requires a Vampire ability to be slotted, and now only functions when you are in Vampire Stage 2 or higher.
Undeath: This passive ability now only functions when you are in Vampire Stage 3 or higher.
Vampirism:
Increased the timer to advance each Vampire Stage to 6 hours from 30 minutes, but casting any Vampire ability will advance this timer by 30 minutes. Feeding as a Vampire will continue to lower your Vampire Stage by 1.
Vampire Stage benefits and penalties are now as follows:
Stage 1: 0% Flame Damage taken, 0% Vampire Ability cost reduction, 0% Health Recovery reduction
Stage 2: 15% Flame Damage taken, 7% Vampire Ability cost reduction, 25% Health Recovery reduction
Stage 3: 20% Flame Damage taken, 14% Vampire Ability cost reduction, 50% Health Recovery reduction
Stage 4: 25% Flame Damage taken, 21% Vampire Ability cost reduction, 75% Health Recovery reduction
