The change proposed with patch 7.3.2 reduces the possibilities of alternative gameplay in my opinion. There are too few of them to be viable right now so it's an impoverishment of the game. "Play the way you like." I like to play in a different way than the meta and have it be viable. So yes, it takes time to think about something and master it, it offers additional content without adding anything. For players who don't want to invest in mastering this specific skill, there are other vampire builds that work so making this skill useless for both pvp and pve is a mistake. I am convinced that more people will abandon this skill line than adopt it. People will pay 700 gold in Riften instead of 800 crowns. A poll could give the community's feedback.

Different change of blood frenzy:

- Same initial cost.

- While toggled on, the Health cost of this ability increases by 40% every second, up to a maximum of 50 stacks and you cannot be healed by anyone other than yourself. At full charge, it grants you 630 weapon and spell damage.
Simmering Frenzy (morph): While toggled on, the Health cost of this ability increases by 40% and Weapon and Spell Damage bonus increases by 15% every
second. You also cannot be healed by anyone other than yourself. At full charge, it grants you 660 weapon and spell damage.

Sated Fury (morph): While toggled on, the Health cost of this ability increases by 30% every second and you cannot be healed by anyone other than yourself.
When you toggle this ability off, Heals up to 25k OR = and >5 stacks=2500, = and >10 stacks=5000, = and >20 stacks=10000, = and >30 stacks=15000, = and
>40 stacks=20000, 50 stacks=25000. At full charge, it grants you 630 weapon and spell damage.*
OR At 20 stacks or more, when you take damage while below 15% Health in combat, toggle this ability off and you heal for 25000 Health. At full charge, it
grants you 630 weapon and spell damage.

* This option seems to be the most relevant since even at level three and without a reduction, the benefit is still slightly more important than the cost in health. Its benefit increases as the initial cost is reduced, making the Vampire Stage 4 and/or the jewelry cost reduction more attractive.

More choices -> more different gameplays -> more specific stuffs -> more equipments to collect -> less weariness -> more game time (and subs) = win-win for everyone.

I have a pve vamplar so my experience is limited and for the pvp content, the mist form is clearly the most advantageous skill for vampire build.

As the patches came and went, I had to rethink my build several times. I stopped playing with the true-sworn fury stuff (crit max cap) and had to change some CP with the rejuvenation nerf.

I hope that these ideas will avoid taking away a whole part of the gameplay that gratifies the diversity.
