I am always for more customisation of the HUD. And yes, while you get used to it for sure, it would still be nice to be able to do a lot more with it.

One advantage FFXIV has over other MMOs for me is that players can survive with much lower HPs. While in others you really had to watch HP like a hawk, in FFXIV you can let people get down to 20% quite happily and they can still be kept up. That extra headroom makes the party frame less important - to me. Often times for me the HP bar over a players head is enough, with the rarer glances to the side.
