I'm always being asked by friends and FC members to make various things from leve items to GC hand ins, leveling gear, etc. There are a ton of mats I don't stock simply because its not worthwhile (especially if I can buy it easily from a vendor) but even then I still use up 4 retainers in crafting materials.
For someone who mostly crafts only high end items, I can see how what I am saying wouldn't apply as much but for those who are a major crafter in a moderately large FC with a lot of different crafting demands the range of items we need to keep stocked is much higher.
Edit: I understand people who DoL want new shinies to gather, and I would not want to deprive them of that, but I really would like to see them recycle more of existing gatherable materials in their recipes and cut down on the number of one-off materials you only ever use once (looking at you ALC and CUL especially)
In terms of other forms of bloating like "buy scrip tokens, to buy favor items, to gather other items to then trade in for even more items before you even start crafting anything with them"; why could they have not allowed us to have a cap of 2000 like esoterics and just have us spend scrips directly on favors (or some other system for gatherers that doesn't take up 12 slots of favor tokens) instead of having crappy space wasters like scrip tokens. Same for unidentifiables, precision alex items, etc, etc
