Holmgang needs an increase in duration from 6 to 15 seconds to be nearly on par with Hallowed Ground.
Inner beast is not like Rampart. The low duration together with the attack speed of the enemy makes it worth a 3s Rampart most of the time. It's more like Shield+Bulkwalk.

But well, did coil with War 2 days ago and it was a piece of cake.

We have still less damage mitigation compared to pld, but way more damage output.
