Sinij stated upgrading all gear to Ascended will increase health by like 900 hps.
Here is some quick math about Ascended gear.
The most Vitality you can get from the exotic gear (armor+weapon+jewelry, not counting runes) in the game is about 758. This is with the Vit/Heal/CondDam dungeon armor set (IIRC the only set with Vitality as primary), Beryl jewelry and something like Valkyrie weapon.
If we assume the same 8% stat increase will be applied to all exotic armor pieces, the most Vitality increase you will get from Ascended armor is about 60, which results in 600 hps. IF you stack ALL your gear with Vitality. Which means Thief’s health will go up from 18,385 to 18,985 (3% increase), Mesmer’s - from 22,662 to 23262 (2.6% increase), Warrior - from 25,952 to 26,552 (2.3% increase).
Again, that’s if you stack ALL your gear with Vitality. If you don’t, you will gain less HPs.
It applies to other stats as well - your character will gain 2-5% increase in stats by upgrading to full Ascended.
OMG the sky is falling, the game is ruined. :)
Infusions can provide 5 Vitality per piece, so 30 Vitality from Infusions in all armor pieces. Instead of runes. Divinity rune set provides 60 to all stats. Lich rune set provides 165 to Vitality.
Big deal.
Ascended upgrade WILL be minor at best. Once they release Ascended armor and if they follow the same route as with rings (no upgrades but Infusions), for many builds it will actually be a DOWNGRADE.
If you see any mistakes in my calculations, please let me know, but until then I am going to say that one should think before getting along with hysteria on other forums.
