Pinnacle Boss/Uber boss Key item drops

Hey all
For the drops of the pinnacle bosses. Instead of having certain items drop at the normal boss or certain items drop at the uber bosses. Rather have the same items drop at both but for normal pinnacle boss have a lower variant of the item drop and for the uber have a higher variant of the item drop.When you progress. You can get the lower variant of the item and then start pushing to get the higher variant of the item. For instance Lower variant Ashes only gives +1 all gems and the uber variant gives +3 all gems. Just and example :)

Thanks!

Pinnacle boss fights should stay just the "tutorial" fights and uber should be the rewarding aspirational content with it's own rewarding items.
