Crafting is a fairly large part of the game and very few people level only one crafter class and keep it like that.

We already have the convenience of quick synthesis, an invaluable tool for bulk items like glamour prisms and dyes, for spiritbonding, and just those times you dont need your stuff to be HQ.

However there's a fair number of recipes which have many layers of crafting required to be made. Just as an example making some end game items requires Eikon Hide, a component of which is camphor...which is made using camphorwood branches. I expect 4.0 will make recipes even more item and layer intensive in the name of complexity and retaining a challenge.

So how about an automated feature which, just like normal quick synth, removes your option to HQ items will quick synth all items required to make a recipe and then let you craft your requested item as normal.

So just as a random example, lets Cascade Synthesis into an Arachne Shirt of Striking. The system will, provided you have the materials, first quick synth twinthread and arachne velveteen. It will proceed to quick synth the rest of the materials(topaz,platinum nugget, and hippagryph leather) without changing your class and begin the craft as normal- provided that you have have the other classes required to make those materials at a certain level. Much like normal quick synth is sometimes locked behind craftmanship rating, Cascade Synth could be locked behind both stats (of the class required to make the item) and level requirements for the other classes.

Well that's my idea, dissect it as you will and thanks for humoring me by reading all this.
