Thankyou guys
Vyuru -Some of it was very wooly but I had been re-editing for a while so I took a break. I had mentioned a couple of times about pairing helm and crafting explicitly but it wasn't terribly prominant so hopefully the edit will have made that more clear
Nuriko – This gets a but complicated but….clothcrafting goes best with harvesting but honestly most of the time at the sort of levels we are talking about here you don't actually take much of a drop in profit if you don't have any clothrafting skill at all.
Mining needs crafting skill because ores don't stack, they take up too much inventory and AH space to be worth selling them individually so it actually increases the rate at which you can make money if you take the time out to get your crafting up enough to 'condense' your ores into ingots that stack and only take up one inventory and AH slot even though on my server this means you actually take a relatively large cut in your gil/ore return
Harvesting is different because almost all the drops stack so you can sell stacks of raw materials which is very AH space efficient. Add to that that a lot of people desynth mob drops like Goblin armour for thread and cloth (the ones you would be levelling up on and selling 1-15) that they can HQ on and sell for profit at around what would be break even point for someone trying to make thread from grass and cloth from thread (even if you bought their cheaper desynthed thread and made cloth from that) so honestly clothcrafting doesn't really help increase your harvesting profits at these sorts of levels.
Red Grass thread isn't even worth making most of the time because while it doesn’t sell very fast people make it because it's a 'big money item' so it's overstocked pretty frequently and then people drop the price to the equivalent of the same amount of raw materials when it doesn't sell. Rather than mess around with that it's usually just easier and slightly better profit to sell the Red Moko Grass Raw
Mining is also much more specific to goldsmithing and smithing than harvesting is to Clothcrafting. You get a lot of random drops harvesting that you could use for alchemy, cooking etc so it’s not quite as closely tied.
