Guild Wars 2

I would add:
- scribing materials that you get often from normal activities : harvesting (lumber cores, feldspar core and jungle grass seeds) + very common mob loot (Strategic defense Map of the Mists (got a real lot of those from just playing WvW once in a while) & pristine feather)
- all grandmaster marks (but not the junk used to create them as those won’t be used elsewhere) Well, it is much more logical to have those than your fractal pages…

I would remove:
- all dowels except the mithril one (only because it is very often used, the others will use lots of slots and be always empty for most players…)
- Unid Fossilized Insect has no place there as it has no use outside being a single vendor currency (on the same map it is found)
- items bought from the mystic forge vendor are probably not needed except those you can’t buy one at a time (mystic crystals and philosopher stones)
- from the current list, I’d really remove all items linked to a single precursor (the now 3 shards of XXX) as the “mystic curios” does the main job for all of them and the currency component is very easy to get on many maps

I didn’t really check the cooking or scribing ones (it is so unfun to use, you only craft there when you want to level it or if you really really need a specific food/item for your guild) It would be way better to have a rework of the crafting system so that it crafts automatically all the subcomponents if all the base materials are available in storage (even if it doesn’t detail what is missing – that part is probably too much work programming wise, more than the feature). If you are told it is not a feature on a not too distant expansion then I guess, your list is the minimum… (probably that no player wants to go the hassle of checking every item there like you did so you are the most competent person to know what is best to make those 2 disciplines bearable)
