At the moment, vitality is in a great place! Besides the fact that hearth hasn’t been programmed in and that its 5-stat perk Regeneration+ is much less useful compared to each other stat tree’s 5 stat-perk.
Lets take a look at each stat tree’s perks.
“Heavy Slash” - 1.2x “Double Slash” damage
“Endurance” - Stamina +1
“Regeneration+” - 1.25x “Regeneration” healing
“Intelligent” - Gain 15 Max MP
As you can see, all of these perks are gained when you have 5 dex, 5 vit, 5 int, or 5 str respectively.
They all have utility and are generally better for a character to try and obtain instead of putting those 5 points into more intelligence or strength to deal higher base damage. All of them except for Regeneration+ which will only be useful for an adventurer early-game since regeneration does not scale with your health bar.
I have two proposals as to how this issue could be fixed in order to make vitalities 5 stat perk more useful and just as valued as the other 3 perks.
1: Move Rejuvenation into Regeneration+'s slot, and add a new skill to Rejuvenation’s old slot.
2: Rework Regeneration+ to buff all healing effects applied to the player by 1.25x their normal healing values instead of just regeneration, allowing the perk user to gain extra health from any methods of healing themselves other than consumables.
This means that warlocks lifesteal would drain more of the enemies health, clerics could heal you for more, and regeneration would still get its healing bonus.
