I would posit a response question in return here, tbh.. If the hairstyle weren't included, let's say it wasn't included in the patch at all.. Would you then be complaining about lack of reward? Despite it already still having 2 mounts (1 tradeable), with a minion, also tradeable, in addition to the i730 gear?
Also, the reward structure and economy being an issue with the game is mostly down to a focus-point on short-term content, over long-term content. Design in some games lends itself really well to this, FFXIV doesn't. If they wanted this to not be an issue, then a heck of a lot more stuff would end up being marketboard-able, and gear would need to last a hell of a lot longer than just a single 4-month cycle, and be significantly harder to obtain than it already is, and older content would need to have significantly more value in the overall content lifecycle. and IMO poor reward appropriation and hairstyles doesn't resolve this, it's a thinly veiled attempt to try and band aid over content that they probably already know full well won't have the same retention 3 months down the line.
