Are you aiming for full on defensive feel?
The way you have this build set up makes me think that the traits in Invocation grandmaster needs to be changed to Shrouding Mist and the grandmaster in Heral should be Enhanced Bulwark. Why? Well you’re getting a lot of damage from just using the food and utility you are. For the set up you’re doing with the traits as a frontliner, I think that the tanky aspects of those two outway the slight damage gain. I do get why you wanted to take them but you’re not going to have perma fury with this build thus Roiling Mists isn’t as effective if you had build around the fury and most of the time you might be using a different facet or not even be channeling Glint and if your not close to someone who can share that boon you’re going to be loosing a lot more than you would gain from having Shrouding Mists. The same problem with Elder’s Force. Yes, you are going to end up with two to three boons (if not more) on you, but not all the time if we have spread out in the raids rather than stacking. The same problem with Shared Empowerment, I would suggest Bolster Fortifications instead. Yes you would get the might as well, but only when you share out the boon which makes it Glint dependent and harder to get the might if you end up needing Jalis more as the tanky build.
I get wanting to keep up your damage, but raw damage, while good, isn’t as good as if you when with a more zerker type build because you don’t have the precision or ferocity.
and right now there is no use for such a spec
