My guess it’s going to be a comprehensive one if the design team is going to put in the changes to the UI system or if they include the item tooltips in skills for easier access.
I’d say changes in certain visual designs of pets if the damage conversion is going to be 100% (an example would be the conduit amulet for Shaman that gives conversions to Briarthorns 100% damage conversion to lightning will have a different look that matches the lightning version. Think about the ones for Conduit version for occulist that gives new designs to Summon Familiar as Aether and Hellhound as Cold) and always balance changes to skills, devotions and items
Soulrend and Shar’zals Worldeater adding skill modifiers would be nice since they don’t have, but I get it if it’s intended to be a support weapon instead for other skills
I do agree with you on the visual sides for pets such as the lightning version for Summon Briarthorn if there is 100% conversion on that skill. Another example I can think of is where Bysmiel’s Grasp turns them and the primal spirit into cold versions of them. Who knows, maybe some day it will happen.
I do also know that there’s a possibility that for Trozan Sigil set, they may remove the lightning visual on the center and replace it with a new design instead since it’s now cold version.
I can assure you that there are so many other pet items that have 100% damage conversion will need to have visual design changes at some point either during patches or when the expansion releases.
And yes, hopefully some day we’ll get them
