Well, unfortunately (but also realistically), the fact that SE intended for us to be capable of playing all classes in the game on a single character doesn't mean that they intended for us to be exceptional in all of them all at the same time. We're given choices so that we can CHOOSE (and change our mind later -- that's the nice part).
We had to do that to a smaller extent in FFXI with things like stat and skill merits. Though the time to change all your merits around to favor Great Katana instead of Hand-to-Hand, for example, would be a much more time-consuming thing than the 2.5-3 hours it takes to completely reassign your stats in FFXIV. Granted the stats probably have a bigger "oomph" behind them than the merits did, but they are also much easier to change completely. (Reassigning weapon skill merits completely from one weapon to the other would take about 7 hours if you were getting a consistent 30,000 EXP per hour, which was a pretty impressive feat when I played. I don't know what the situation is like now with Abyssea.)
Hitting the "reassign" button once at physical level 17 gives me 23 stat points and 20 element points to work with, and you can do that twice in the first 30 minutes (once when you have no cooldown, and then a second time when your first cooldown is up). It would be nice to have the option for a full re-assign in town, but it's not horrifyingly bad considering the only stat I don't use at all on Conjurer is STR (I use VIT for HP, DEX for Radiance, and the rest is obvious).
I'm not sure about botany and mining, but someone posted something a while back that suggested that the crafting classes each favor a single stat. Armorer was VIT, Blacksmith was STR, Goldsmith was DEX, Alchemist was INT, and I can't seem to remember the others... I believe Culinarian was PIE (har har). They had an ability or something of that sort that would temporarily increase the associated stat. That could just be some sort of incentive for people to level crafting classes and not just their DoW/DoM jobs, rather than an indication of what stat is important, but SE did say that there were "clues" in-game about what stat affected which type of crafting.
Edit: Just more content, as if it needed any more content. :\
