Encase In Jade needs to change. Here's my idea

My Idea. As a warbringer lover
Change the 6% max life as guard per stack to 3% less damage taken from hits per stack. Allow it to mitigate all hits during the "Guard window" -- 5 second guard window. Then have the same cooldown of 10 seconds. It doesn't have to have any PDR and you can consume the stacks early to get a little bit of reduction if you want. This will also save it from it's awkward interaction with fortify cry guard as it prevents the stacks from gaining while you have an active guard.

This would mean we can use it when we see a big pack of monsters or if we get swarmed and can maybe give us a chance to leap slam out if. I think thematically this suits the warrior more and would be way more functional. Currently right now the guard just gets eaten up too quickly to be of any use over the replenishing guard from fortifying cry. Even bosses it would help alot against repeated attacks for example against xesht hand slams or against map bosses with tonnes of attacks speed.

I also think this could be a good way to change the wooden wall ascendancy to make a more interesting totem ascendancy and compliment the current turtle charm more.

In it's current state it's wayyy too situational and is only really useful against boss 1 shots for increasing peak EHP (mainly ele). Outside of that it is actually kinda useless and jade heritage is only useful for the stacks of jade 10% PDR.
