With multi-battles being more common - probably more common than 1v1 - how do you feel about making all item usage global, affecting all active team members? (the same would happen to enemy tamers though).
Don't think about Revive-like stuff yet. Just stuff like potions and status healers.
I'm just trying to find ways to streamline the UX flow wherever I can. It will be fine either way though.
Side Note: separate efforts will tackle the issue of item-spamming which made battles uninteresting in previous games.
