Game Noob needs Jugg advice

https://pobb.in/_oGEMiUOCXpN

So I am just trying to complete my atlas and I have cleared a bunch of t12 and 13 nodes. I am trying to do the 14+ boss kills for Maven but I seem to be dying a lot. I'm just wondering if there is anything in my build that is a big red flag or something I should change.

I feel like I have a lot of armour, a lot of DPS (compared to my first toon), I run out of Mana a lot with my auras up but still I feel I can't run anything over t13. Any help would be appreciated and I will also accept, if my build is on the right path, just get better. I just started playing a month ago so I still have a lot to learn.

Thank you!
