Newbie here making his input. I can honestly say I would like to see unlimited arrows for no other reason than I don't really see many other games using consumable ones. I'll use Guild Wars as an example. Rangers don't need to buy arrows there, they just need a bow. If you decide you want to play another class and make a new character, you don't see any of them needing to purchase consumables ever and they are just as fun as playing a Ranger. If you move from Guild Wars to FFXIV (or XI for that matter), you will probably be turned off by the fact that your favorite archetype is basically a money sink all the time. It simply isn't fair if you look at it from the respective points of playing other DoW classes. On the other side of the spectrum World of Warcraft does have consumable ammos for ranged weapons, however classes that use them also have melee weapons to deal with threats if they run out at an inopportune moment. FFXIV Archers simply do not have that, they get to punch their enemies which does considerably less damage than an arrow.

So for the tl;dr version: I like the idea of unlimited arrows, but if that won't happen give archers a melee weapon to help deal with the inevitable moment when those arrows run out.
