RNGs are terrible systems. Especially this one FFXIV has where you are more than likely to be punished for 10% rather than rewarded for 90%.

We dont have to do tokens to get gear, just give people gear. Systems are smart enough to know what class you are and be able to give individual gear rewards based upon that and whether or not you have the item. You run the instance, you did the work. You should get your gear. That simple. RNG for loot distribution is one of those archaic MMO systems that needs to go the way of camping.
