Stat reset is going to be implemented on a sliding scale, 10mil for first reset, 20 for second, etc, going up exponentially. This is meant to be a one-time service to fix a build messup or to respec for a different role. It's not meant to be a replacement for making alts.
With the rates are, it's still easier to make a throwaway alt to leech pure forger/potter builds rather than get them up with a battle build then stat/skill reset for crafting. Really the idea is to allow people to fix bad builds, or to make major role changes like say switch from Spear LK to 2H Parry LK. Or when PvP starts up, allow people to reroll their PvE characters to WoE/PvP builds without having to start all over again.
As for headgear, there's no longer a concern about them being "OP". The standard right now is to make our cash shop match iRO's cash shop (with exceptions like no Battle Field Manuals, adventure packs, etc). Obviously really good headgear will be priced accordingly, so don't be surprised if you see some hats costing upwards of 5mil.
@mail will be removed as soon as I can implement an item to replicate its functionality.
