You realise the mechanic to limit this stuff already exists, don't you? Soldiery tomes have a cap and could be used to purchase items necessary for crafting. You could make items which require items dropped in raids which count towards your weekly limit. There are possibilities here, but people are too short-sighted to see them when it comes to crafting.
Besides, anyone who's done even a little bit of crafting knows how much work goes into capping out your skills in order to be able to craft the high level items. Work, and gil, lots of gil. Why shouldn't we be able to see some kind of return on our investment? It takes a mere ilvl 70 to beat a high level dungeon and walk away with ilvl110 gear, and that's somehow more 'worthy' than spending a lot of time, patience and money investing in a craft.
