To get Tricks of the trade (lv15 ALC), I just bought 99 phials of Ether and spammed leves.
Weaver is the most slow and difficult craft to level up, that's what lots of people I know say, and what do I need? Weaver -.-
I think Weaver is long and difficult because it requires mob drops, and not gathering items (Linen is the only exception).
Then, you need leathers and skins, so LTW must play his role, and then you need feathers and reagents from gathering...
A BSM just need his raw piece of metal to smash the hell out of that, to get badass weapons (yes, there are some more complex recipes but not as many as WVR have).
