Potions (such as Hi-potions, Ether, ..etc.) see little to no use in FF14 unlike other FF games, i've been thinking, why not rework them to have them replace restorative abilities ( second wind, lucid dreaming) with a 20 sec cd per use, some limitations can also be placed on how many can be equipped, let them also be used by all jobs while greatly reducing self-sustain abilities currently present (on Tanks specifically).

Speaking of Tanks, why not give them some crowd control status effects and make them associated with their aoe abilities on 30 sec cd, for example (PLD:SoC. & GNB:BowShk. = blind effect for a short duration) , (WAR: Orog. & DRK:AbysDr. = Pacification effect for a "shorter" duration).
