Walking Calamity isn't fun + rework idea

the problem

Walking Calamity isn't fun:
-it clutters the screen, so I don't see much, this can be especially detrimental during boss fights
-there is no meaningful gameplay around it: either I press a button and everything around me dies or if its tuned weaker, it still damages everything around me without interacting with the monsters in any meaningful way
-the glory is too easy to generate, it almost feels like a skill with glory for people who do not want to spend any effort on generating glory

I would like to see this skill reworked:
-fix the screen clutter
-add a way to generate glory, so it feels more like an ultimate to use after having made at least some effort to generate the glory
-make it more interactive, so it changes up my playstyle in a fun way during the ultimate duration instead of merely being a 1-button-press screen clear

a first rework idea
I actually don't know what would be a great rework that fits my own critera. Maybe other people here can suggest something.
What comes to my mind right now is somethingn like this:
-generate glory when performing bear attacks (or maybe shapeshifting attacks, to support hybrid builds?)
-replace the skill effect entirely (old effect completly removed, so no automatic rage generation, etc.)

new effect:
-while this skill is active bear attacks are enchanced in different ways, this is also shown visually, but in a more subtle way like fiery bear claws and the bear skill animations changing
-skill changes:
-furious slam calls down a meteor after a delay if performed as enraged slam
-vulcans have their duration halted and their limit increased
-fissures from fury of the mountain are triggered by meteor impacts, activating a fissure triggers vulcans touched by the fissure
-attacks empowered by Ferocious Roar reduce fire resistance
-during rampage the player can dodge roll and slam while continuing the rampage

Maybe the New Effect could also include like +1% Max Fire Res and +1% Fire Res or some Fire Thorns while you have the effect. Or even just some % of Phys Dmg taken as Fire.

I like where your head is at. These are the kinds of design concepts I hope to see more of in this game. (But not slathered EVERYWHERE.)
Same thing w/ Infusions, and I'm sure there are many more areas that could take some influence from this type of concept w/o becoming generic.
I think they're just fundamentally against it because of the design complexity it creates.
