Guild Wars 2

Looking for any thoughts or criticisms on this build. I’ve been trying to find a balanced power build for PVE (dungeons mostly) that has a good mix of survivability and damage. Without food buffs it’s looking like:

Power: 2279
Toughness: 1246
Vitality: 1156
Crit Damage: 59%
Crit Chance: 47%
Armor: 2166
Health: 20772

Different itemslots have a different Stat-to-critdamage ratio. on some, you get 1% crit damage for 16 statpts, on some other (the exotic jewels) 1% is worth 5 statpts.

The cheapest way to get crit-damage are Perfect Ruby/Beryl Jewels, so i would put them into every possible slot.
Legs, Head, chest (and rings and back-items) have the worst ratio, so i recommend changing them to something without crit-damage
