I feel like FoF, FoW and FoE should become temporary buffs that interact with MP like they used to in 1.2. I don't like how melee have a resource that isn't interacted with it at all, especially when lore-wise we are using our aether in some fashion on every job.
- FoF could increase DPS by a % while draining 50% of your MP.
- FoE could ignore positionals and increase chakra gain rate while draining 50% of your MP.
- FoW could refresh Greased Lightning with the 4th stack, increase movement speed, and recover MP (either 100% over the duration, or 50% and separately allow MP to recover by 10% every time a chakra is opened).
Give each of them an equal duration and 3x recast so you have one up at all times. This could give MNK the feeling of fast mode and strong mode by losing that 4th stack of GL for a period of time. I liked the concept of that in SB but negating GL completely just felt slow and bad, gaining and losing 1 stack feels like a good compromise.
