Way phoenix down's are now in the game, they are nigh useless. Can only carry one on you at a time, can only rez people in your party, and you can't be in combat.

At this stage of the game, the last two arn't really an issue anymore, someone in your party dies after a fight, swap to sch/whm or if in an instance have them release back to start.

My suggestion to make Phoenix Down something everyone will carry on them, is to allow us to rez our self with it. If you die with a phoenix down in your inventory, and arn't in an instance, have a prompt ask if you'd like to use your phoenix down to resurrect yourself.

They wouldn't be the "in demand" item, since lets face it, how often do you die in the over world. But it would be a neat little niche item that could save you some leg work and a teleport cost. Wouldn't really be a big advantage since you can only carry one at a time, and they aren't craftable.
