Honestly the biggest problem I had with gear in XIV was that it wasn't needed until you got to 50 more or less. I don't know how often I saw people exp in gear that was not good to begin with and that they outleveled 30min into the party. In the end though it didn't matter because people just dinged too fast to expect anyone to buy new gear for every level (Especially in PL parties, but this applied to normal parties as well imo). If you dinged and the party ended sure you might get a new weapon before the next party, but generally I had maybe two gear setups and maybe three weapons per 1-50? Granted I was mostly mage/support so it didn't matter as much for me, but I saw the same thing on a lot of others too.
I agree that it isn't fun always getting new gear from loot all the time, but with quest based leveling it will probably be like it is in most mmos nowadays. I doubt crafting will matter much until lategame, especially with the system where gear that is spiritbonded = bound to your character. Combined with a probable high speed to cap I sure won't spend gil on gear I will just have to NPC as soon as I ding 50 if I get gear for free via quests.
Personally I'd like a combination of systems where leveling isn't fast enough for gear to be obsolete in an hour, crafted gear has its place alongside quested gear (that then would have to be less frequent as a reward than in most mmos) and I think the only way to get something like that is if you make a game where endgame is only a part of the game and not the only thing anyone cares about.
We will just have to wait and see how it turns out I guess, most answers will come with beta I think.
