Crafting-fiend here, constantly running out of space for my crafting mats (all DoH & DoL 50+). Okay and also a pack-rat.
Sure we can get additional retainers (already more than what is good for me), but it is kinda inconvenient to have your mats spread out on several retainers, and not really helping immersion levels.
So here an idea to increase immersion levels and make things easier for pack-rats and crafting-fiends:
Have a crafting "station" in your FC room or house, where you can have a locker, chest, whatever which offers you space for storing your mats and maybe also gear. And/or a "crafting station" which offers storage space for mats and also an armoire that is actually worth it's name and where we can store our gear, no matter if an NQ ilvl 10 hat or a relic weapon.
