Increase Reward Cap somehow? through JP categories?

[Gwydion]

Hi SE!
Beastmasters can cap Reward potency/recast with just our Reforged AF Body/Legs/Feet....but there are so many pieces to play around with! Can you possibly give us a higher reward cap (and tell us what it is!) so that we can use more reward pieces or perhaps make different reward sets?

Thank you!
