Your dmg and toughness is way too low. And it’s mostly due to the fact that you lack CHC and CHD. You have no emerald in your weapon so there goes 5 tiers. Missing 20% CHC, there goes another 5 tiers. I have a hunch you are missing a bunch of CHD and Area Dmg (AD) on gear.
if you are squishy you should be using Final Service passive. Also another reason why you would be squishy is because you do not have all 13 ancient pieces. It’s 4% per ancient = 52% dmg reduction. Your sheet should be reading 40 million toughness. And 750% dmg per ancient. Also this is under the assumption you have a level 99 LoD gem.
I’m also viewing this on a phone, so I can’t dissect your gear any further. Till I get home.
