Guild Wars 2

This is the only stat in the game that doesn’t show its value. Lets say i have 1560 Toughness = 2727 Armor. I have no idea for how much less physical dmg i take, because the tooltip doesn’t show me that. Is the dmg reduction 5%, 10%, 15%, 30%?
Why the tooltips for ALL other stats are simple and clear, why is the Toughness/Armor only exception here?
1050 Power shows exactly for how much more dmg i do with my weapons, 500 Vitality is 5000 more health, 2050 Precision = 54% crit chance, 900 Ferocity = 210 crit dmg and so on. And 3000 armor is? How do i check it? Is it something around 5% dmg reduction only (useless stat) or lets say 30% dmg reduction (not bad at all)?

I know there must be a math for it, but why should i use it (i hate math btw), if Anet could simply add these numbers in the game?

Because Armor is not a percentage reduction.

This is the formula for damage:
Damage done = (Weapon strength) * Power * (skill-specific coefficient) / (target’s Armor)

What do you propose they tell you based on your armor?

A quick wiki search will bring you to the following formula:
Damage done = (Weapon strength) * Power * (skill-specific coefficient) / (target’s Armor)
Or to put it more simple: If something did X damage to you without toughness (so 2167 base armor), with Y amount of toughness it will do:
Damage done = (X * 2167) / (2167 + Y)
With your mentioned 560 Toughness you should get roughly 20.5% damage reduction.
As you may notice, the reduction changes depending on your base armor, so it’s different for each class.
Also, 1050 Power does not show how much more damage you will do, It also works with some formula dependent on many variables.

But at least i can see numbers of dmg increase on my weapons: for example Warrior Axe aa without Power = 249 dmg, with 900 Power = 472 dmg, with 1200 Power = 547 dmg. I know that i won’t hit foe with exact smae numbers shown on tooltip, depends on foe’s Armor and other dmg mitigation skills, but at least i can get get some picture about how much dmg increase i can get with more Power, which is not the case with Armor. Anet should add some rough numbers at least, just that we get some picture about it as we get it with Power numbers.

So with 1200 Power i can see that my dmg will rise up for more than two times! That’s all i need to know, while with 1200 Toughness/3088 Armor i don’t see any kind of numbers.

But thx anyway for your math
