Healing items in the game can be changed to a single item, removed from the loot table with 2-3 charges that will recharge over a long period of time. Players will have this when they spawn in game, or could add charges as you progress with items. Item heals a certain amount, HP then shield; it’s a single heal item to make it less cluttered in the loot table. And removes complication in healing when there’s already a lot going on with items/weapons. Also, with healing items removed from the loot table, will allow for more drops of gear that players are seeking. There is an issue where there are so many weapons/gear that the drop table is cluttered and you can get to the final floor in Ascension and your team never finds that last piece you’ve been seeking.
Additionally/alternatively, you could have HP not consumable item healable, but only slowly out of combat. And the healing item is just for shield.
