Why is Vigor Alpha so bad?

My Titan Weapons/WP brute was still crying for Endurance even with Quick Recovery (especially since I'm using Eradication for the many PBAoE attacks, and that set doesn't give much in the way of End Reduction). And I happen not to have slotted much +Acc either, and Titan Weapons has no native boost there unlike other weapon sets.

Vigor should fix everything for me, while giving a nice boost to my healing.

For my Regen Scrapper char I already have Spiritual. I can't imagine a better one.

Yes, Musculature and Intuition have +damage. I think Intuition having a damage component is an interesting development choice - not a bad one, just an interesting/unique one.

I wanted Vigor on my WP tank. The accuracy would be useful because I have Kinetic Combats in my melee attacks. Unfortunately, Vigor Core Paragon is not yet working with High Pain Tolerance. Spiritual Core gives more +Max HP. It's a nitpicky amount, but I'll be happy when it's fixed!

Vigor is also particularly good on dark Miasma toons. The heal portion helps the heal and the servant's heal, End redux is extremely useful, and the accuracy is helpful in most of the powers as well.

Also almost all of the incarnate powers benefit from Heal, end redux and accuracy, but none of them benefit from +rech.

I can also see vigor being good in Time manipulation. I find the set somewhat end heavy even with chrono shift and the set has 3 different heals that can benefit from it.

I can see it being pretty useful on a TW/WP character. Endurance for the heavy costing powers, heal for the regen/hitpoints, and accuracy so you don't miss.

I think Vigor is the best of the new Alphas. I have several characters who benefit from both increased endurance management and increased +regen.

Reusing an analogy invented by others in the Scrapper forum, our character's survival mechanisms can be viewed as a 3-dimensional solid, like a cube but with sides of unequal length. The length of each side of the solid is how good our character is at defense, resistance or HP recovery. Make any one side bigger, and the shape gets bigger inside. The bigger the volume you end up with, the harder you character is to kill.

Most forum goers today probably have some awareness of how defense and resistance have non-linear the effect on survival time the closer you get to 100% resistance or 45% defense. (59% in iTrials.) HP recovery is not like that. Adding a given amount HP/sec recovery always cancels a proportional amount of damage/sec, while adding a given amount of DR or defense allows you to absorb or avoid increasing (average) fractions of total incoming damage.

This means that when you already have a lot of HP recover, it can takes a lot of additional HP recovery to make otherwise deadly amounts of incoming damage survivable. But if you have a lot of defense or resist, it may only take a little bit of additional defense or resist to make otherwise deadly average amounts of damage survivable.

Characters like Regen have very tall HP recovery sides to their "survival solid", but a very short resistance side and no defense without dipping into pools or IOs. Willpower also has a very tall HP recovery side (though it doesn't max out quite as high as Regen's), but out of the box it gets a nice base of defense and resistance. Regen gets the most bang out of Spiritual Alpha, because a lot of Regen's +HP is tied up in clicks, which Spiritual both makes stronger and recharge faster. Willpower gets very little out of +recharge, but benefits from strong +heal enhancement. Because they are already so good at HP recovery, it takes a lot additional to make them noticeably stronger, but fortunately Vigor and Spiritual do give pretty big increases to them.

Something like SR or Invuln may not seem like a great place for Vigor, but the fact is, they have very large Defense and/or Resistance sides to their survival solid, and small HP recovery. Using IO sets can earn them a bigger +HP recovery side, as can taking a power like Aid Self. But the real kicker is what happens when they take Rebirth Destiny. Rebirth is fantastic on characters with small HP recovery sides to their survival solid, because it helps dramatically increase that side. Because the other two sides can already be very big, the increase in total volume can be extreme. At Very Rare, Rebirth's smallest boost is +100% regen. With Vigor, that becomes +145%.

One of the most endurance hungry characters I have is a melee Night Widow. Before Vigor came along, Cardiac was the only thing that gave her the for endurance management to fire her max-DPS attack chain without running out of endurance. She also has Radial Rebirth for the wonderful +regen. Core Cardiac's DR enhancement does very little for a Widow, as they have only one enhanceable source of damage resistance, and only to Psi damage. Therefore, Vigor was the clear winner, offering increased HP regen from Health and Rebirth and still good enough end management to fire her primary attack chain without stopping.

I also have a BS/Invul Scrapper with Rebirth Destiny, and I also am thinking hard about switching him from Cardiac to Vigor, even though I will lose being at the Scrapper cap for L/S DR. The reason is that, even with Cardiac, his resistance to other damage types isn't that great - the survival solid just for those damage types is smaller, so making the HP recovery taller has a bigger effect. (I'll have the choice, I can switch to Cardiac for L/S-heavy content and to Vigor for content rife with "exotic" damage.)

Of all the new Alphas, Vigor is definitely my favorite.

Yeah this went to Live a little faster than I expected.

Just yesterday I suggested Vigor for a SG members Earth/Storm/Stone Troller.

Was in need of ENDRED, has no resists to buff, and Vigor buffs the healing to not only her O2 Boost, but bigger heal for that Earth's Embrace, with tacked on +ACC.

I did think of suggesting Intuition as it seems to go really nice with the combo, but it doesn't help the endurance issues at all.
