Vitality, Toughness And Healing Power
How do we build defense ? Healing power has a really bad reputation, toughness and vitality were always around but never really a big topic. Today I want to pick up this highly subjective topic and analyze the ideas of the ideal defense.
TL;DR
The priority for defense is as follows: Toughness > Vitality > Healing Power.
If you’re playing guardian you can consider this as your priority Toughness > Healing Power > Vitality.
Toughness doesn’t help you against condition damage, so make sure to get at least a touch vitality as puffer (I suggest at least 14k health in total).
Let’s analyze first, how well these stats scale, and what exactly they do.
Vitality
Increases the health pool and is useful against burst damage and degenerative damage. It scales as follows:
Vitality * 10 = Additional Health
Toughness
Increases the armor directly and is useful against direct damage. It works as follows:
1 Additional Toughness = 1 Additional Armor
Healing Power
Increases all healing done (regeneration as well as direct heals). It scales NOT with the healing done by reviewing someone.
Is scales to 0.125 for each healing power for regeneration, but has it’s own coefficient for every heal, so there’s no all in one formula for this stat.
First I wanna take a look on how toughness works. After that I will analyze how well healing power scales with class specific heal skills and compare them with the value you get from building toughness. I will do some further calculations on guardian, since he uses healing a lot.
Toughness Vs. Vitality
Since toughness reacts to damage I will hold vitality against calculations with increased armor on examples I already did on Berserker’s Gear analysis.
To keep theory as close as possible to practice I will boost each attribute by 798 + 125 (which is the highest primary stat you can get on amulet + jewel) on a level 80 character.
Vitality + 923 = 9230 Bonus Health
Toughness + 923 = 923 Bonus Armor
Berserker’s Gear Calculation, 10 Hits
(258 * 1839 * 0.666 / 916) * 10 = 3445 Total Damage
Berserker’s Gear Calculation, 30 Hits
(258 * 1839 * 0.666 / 916) * 20 = 10335 Total Damage
Berserker’s Gear Calculation, 100 Hits
(258 * 1839 * 0.666 / 916) * 10 = 34450 Total Damage
Berserker’s Gear Calculation, 10 Hits + 923 Toughness
(258 * 1839 * 0.666 / 1839) * 10 = 1718 Total Damage
Berserker’s Gear Calculation, 30 Hits
(258 * 1839 * 0.666 / 1839) * 20 = 3437 Total Damage
Berserker’s Gear Calculation, 100 Hits
(258 * 1839 * 0.666 / 1839) * 10 = 17183 Total Damage
Comparison
Damage “eaten” through Vitality
10 Hits = 100%
20 Hits = 9230 / 10335 * 100 = 89%
100 Hits = 9230 / 34450 * 100 = 26.79 %
Damage reduced through toughness
10 Hits = (1718 : 3445 * 100 - 100) * -1 = 50.13% Damage Reduction
20 Hits = (3437 : 10335 * 100 - 100) * -1 = 66.74% Damage Reduction
100 Hits = (17183 : 34450 * 100 -100) * -1 = 50.12% Damage Reduction

Health gain per second with and without additional healing power:
Guardian
30 Recast - 1.25 Cast Time = 28.75
4555 / 28.75 = 158
(4555 + 0.7 * 923) / 28.75 = 181
Warrior
392
439
Engineer
20 - 0.5 = 19.5
(2520 + 390) / 19.5 = 149
((2520 + 0.5 * 923) + (390 + 0.125 * 923)) / 19.5 = 179
Ranger
29.5
(2340 + 4920) / 29.5 = 246
((4920 + 1 * 923) + (2340 + 0.125 * 923)) / 29.5 = 281
Thief
15
4344 / 15 = 290
(4344 + 0.6 * 923) / 15 = 327
Elementalist
18.5
5000 / 18.5 = 270
(5000 + 1.2 * 923) / 18.5 = 330
Mesmer
21
5560 / 21 = 265
(5560 + 1 * 923) / 21 = 309
Necromancer
23.5
5240 / 23.5 = 223
(5560 + 1 * 923) / 21 = 309
Deeper Guardian Analasys
No Healing Power
Hold the Line = 22 HPS
Ray of Judgment = 16 HPS
Virtue of Resolve = 28 HPS
Shelter = 160 HPS
Total HPS = 226
Additional Healing Power
Hold the Line = 43 HPS
Ray of Judgment = 29 HPS
Virtue of Resolve = 46 HPS
Shelter = 181 HPS
Total HPS = 299
(226 : 299 * 100 - 100 ) / -1 = 24.44% more healing
Toughness for 1 hit
(258 * 1839 * 0.666 / 916) = 345 Total Damage
(258 * 1839 * 0.666 / (916 + 923)) = 172 Damage
345 - 172 = 173 damage negated
Increased healing power:
299 - 226 = 73 damage negated
Vitality is in the end, only a puffer which has to be filled up again. Although toughness doesn’t help us with degenerative damage, it’s effect is so massive, that it’s definitely the stat you want to go for, once you have a health pool you feel comfortable with.
Healing power is in a weird position. No other class than guardian could somehow profit from it, since it scales so strange. However, considering you’re healing your group as well and keeping in mind, that toughness is only a modifier for your healthpool - that means, toughness doesn’t help you get up, once it gets empty - healing power is a choice you can make if you play guardian. I would never suggest it to any other class in order to build defense.
