Bulk Synthesis?

[gamesmart]

I like this idea, but I'd put a few other restrictions on it. Only items that stack, and very low, if any, exp gain. I could imagine the economy shattering if people changed to only level on items you could make with one click.

I do agree with that. This was really just something I came up in about 2 minutes, so obviously it's not fine-tuned to the potential and probable implications of implementing such a system. I didn't think of the xp gain side of the system due to me having had all crafts max level for quite a while now, I'll add this to the OP.
