Opinions on the build (btw it's awesome)
Why does anyone use Azurite for anything? You can get vitality through other stat combos.
ALWAYS use berserker or valkyrie jewels over any other item slot. The jewels give 1% crit damage for 5 stat points. Most other places it’s 10+ per 1% crit damage.
You’ll need to re-do your gear for ascended pieces.
You generally don’t want to go above 2800 armor for survivability. After 2800 armor, vitality gives better returns. You only keep going if you want a tank build.
I would recommend Strength in Numbers in place of Retributive Armor. Even with almost 1900 toughness, you still get less than 100 precision. With Strength in Numbers, you get 150 toughness and you can change some toughness on your gear to pick up precision. It also helps nearby allies, which Retributive Armor doesn’t.
Not sure if Sigil of Force and Sigil of Accuracy stack. Either way, Accuracy isn’t that good unless you have extremely high crit damage. I would go with an on-crit sigil like Fire (AoE) or Air (single target).
You seem to be lacking a lot of boon output to take advantage of Altruistic Healing. AH builds often go for Inspired Virtues (5 points in Virtues line) so that using virtues gives boons, especially the 3 might stacks on VoJ.
I recommend going with Blind Exposure (VI in Radiance) over Signet Mastery and using Shelter as your heal. If you time Shelter properly (takes some getting used to), the damage you block combined with its healing has left you with more HP than the larger heal of Signet of Resolve. As an alternative, Inner Fire (IV in Radiance) is good for WvW or dungeons with lots of burning.
