I have to add to this, just to give an idea. There is (I typically stick to the area south of Dragon Head that has the obnoxious name) a series of level 30 leves that give ~21k exp per turn in. This doesn't seem like much (considering the amounts mentioned). But, leveling my Cloth crafter last weekend this is the breakdown of A SINGLE LEVE exp (Seriously, it was this good ~36-50, obviously there was a crafting drop-off in exp).
Flax -> Linen Thread Batch synthed for ~1k exp (dropped to 200ish) (will only count enough for one leve)Say, 27 synths
Linen Thread -> Undyed linen cloth, ~6k per synth, consitentenly HQed this, so, I would then do 18 Cloth
Finally, to make the Linen Tights (3x turn in leve).
This would take 2 linen Cloth, 1 linen thread, roughly 8k per synth, 3 synths per turn in, 9 turned in total
so, we have:
207000 (Just on crafting)
followed by (21,000+ (21,000*2))*3 for HQ turn ins
So, almost 400,000 for turning in a single leve.
As you level up (above 40), the crafting exp drops down as low as ~50k, but you are still walking away with over 200k per leve.
