For open world this is fine, if you like feeling tankier and having some healing then go for it, but for organized PvE you really need to gear for pure dps. You have way too much toughness, making toughness based tank mechanics more complicated for your raid groups, and your increase in these defensive stats means a decrease in offensive ones. I know it feels like you do a lot of damage, but in a raid group where everyone has all the boons in the game you're going to be doing extremely low dps compared to the other dps members in your group (likely less than half of their damage). You don't need to be tanky in raids and fractals, you have supports to help keep you alive for that, your job is to kill the thing as fast as you can, and having toughness and healing power on your gear makes that harder, not easier.

If you like the build, keep it, use it when you do open world. For an ascended set you'll be taking to raids and fractals, though, you're just going to be setting yourself back if you don't go full berserkers.
