For weaver and leatherwork blue scrips, be on lookout for days they have crafting or gathering gear on the list. Those generally have easier ingredient requirements and none of that stat essence stuff that all combat armor requires. Same goes for crafting tools actually. Same level items that on battle side would need titan ingots, for example, on craft tools want titan nuggets instead.

For red scrips, stated above, try to avoid the adamantite requiring recipes. The aurum Regis is way cheaper and easier to acquire, either through retainers or nowadays, from vath.

I actually think that is a bit unfair. Each and every level 60 material can be acquired through retainers, except adamantium. That places especially the blacksmiths and armorers to worse position.
