It would help the dev adjust the balance in subsequent patch if you can rationalize why all shield throw build is not viable by end game. Other knowledgeable forum member (not me) might also be able to improve your build in ways that you might have missed.
Just the change of ring of shield kills them, they all need to take it in end game ( 200 + corruption ) but they also need to take paladin in master.
Have not played the new patch.
But guess 800-900 HP max ress in phys + poison and some low CD movement skill should be okay for the boss fight there?
If the build is correct, yes.
