I am currently level 80 and had some problems with the survivability.(also my minions died a lot) So i decided to try and add some dodge + ward. (20% dodge)
I am using the following uniques:
Helm: Boneclamor Barbute
Belt: Ward Trail
Weapon: Undesputed (only one) it is a good dps boost until you get the endgame weapons
I also put 10 points in Hawk Wings. Yes, the damage is little bit lower, but oh boy does the dodge + ward make a difference. I no longer get oneshot by projectiles and I can tank way more. (better for arena)
So whoever struggles with survivability later on can try this. My items are still not perfect thats why I only have 20% dodge, but it still makes a world of a difference.
Maybe there is a better way to go with survivability, but this is what works for me for now at least.
