Yep, this is exactly what I was going to post. Also, pro-tip for those new to crafting, the lev. 15 skill from weaver, Careful Synthesis,is one of the best skills in the game. It's a 100% success chance, and gives about 5 less progress than what standard synth does. So if you only have 10% durability left, you are guaranteed to complete the craft if your progress takes it to 100%. Rapid synthesis, the 15 armorer skill, is also incredibly useful for anything that has a very high progress bar (90+). It is basically like a triple standard synth, but at only 40% success. If you combine it with steady hand however, it bumps up to 70% and becomes incredibly valuable for saving progress for HQ attempts.
Just some food for thought.
Which classes can Careful Synthesis be shared between? This sounds incredibly useful-- thanks for the info.!
All. Every Level 15 ability (if you check the tooltip) is "Disciple of the Hand" requirement, rather than GSM/WVR etc. Some are definitely more useful than others (with the WVR one probably topping the list, allowing you to squeeze the most out of that last 10 durability), but it's quite worth getting them all up. All of the <15 crafts can be done with mats bought from the guild vendor solely, or if you are willing to travel you can pick up the "base" components from other guilds. E.g. working on GSM last night, they use buttloads of copper ingots at low levels - past about level 10, it's a waste of time to do yourself (but fairly easy to HQ, if you're after quality components for HQ gear) - but go to the LTW guild, and they sell copper ingots for 9 gil each (as they're needed in a handful of lower LTW recipes). Leather circles can be bought from the GSM guild in return (reciprocal arrangements, ya know?).
Of course, this peters out around 15 - but by this stage, you're actually spending significant time out in the field gathering mats. On MNR, I blew through 1 - 10 in about 1 1/2 hours (even then, it was easy paced), so my window of getting copper ore (while it was exp-worthwhile) was small. Much rather pay 6 gil for 3 ores into an ingot, or 9 gil for a finished product, than take 30 sec to find pull out 3 ores, for about 50 exp total. 10 - 15 was slower, so I worked on the iron veins outside Copperbell Mines, working in an occasional leve to ding. Consequently, I have about 2 stacks of Iron Ore, for when I move up the ARM/BSM ranks. Higher level gathering means more time in each tier of materials, means more materials.
Funnily enough, I'm not hugely concerned with endgame at the moment (a first for me in an MMO), as I'll be leveling a battle class (LNC -> DRG), it's subs (MRD & PGL), a crafter (probably GSM) & a gatherer (MNR - from GSM of course), and they'll be roughly concurrent. It may take a while ...
