cammie your guide still helps alot people learn crafting from the prospective of just analysing what you have and seeing if you can optimize it or rearrange some things to suit your needs better.

i remember reading through it at the back end of hw along with other things to see if there was new things to gleam from it. ive been crafting since arr launch but the more you know so to speak.

as for xpac... one of the best opportunities will be desynth if its like hw and sb launches. so much super cheap gear to buy you can power level to the current or new max super easily. and then just sell all the mats back on mb to either break even or more likely to make a profit. even if you break even it means all dungeon gear will be easily broken down to new mats and those will be worth good gil for awhile while everyone is levelling.
