Two quick suggestions.

One, I would really like if there were cosmetic options for WF in the store. Perhaps a "Base Color" dye, similar to the hair dye for fleshies.

Second, I would be willing to pay even up to 10x current TP costs a pop to buy permanent Gold Seal henchmen. Perhaps these can be labeled "Platinum" hirelings. Really this wouldn't be terrible unbalanced, as the hirelings right now are level based. So they only have a window of use per character. The hirelings themselves don't need adjustment, this just takes away the timer element. "Gold" and "Store" hirelings would still have a place as most people woudl only buy 1 - 2 specific platinum hirelings (likely the clerics) and then supplement with gold and store as needed.
