I think they should've just did crafting/gathering like every other MMO's. When you're in the field leveling a class, say blm for example, and you're a miner you can mine while you're in the field. I never understood the archaic design SE took toward making each crafting skill an individual job.

There's a lot of things that I question in design (they seem a few years behind most others), the housing debacle is another one, I never understood why they'd limit housing like they did. Or the inability to whisper to people in dungeons, the ability to see a TP bar in groups (which they're finally adding...) etc..
