Suggestion: Increase Armoury chest/inventory
Armoury chest
Armoury tabs would be extremely helpful for players who need to manage their gear. Armoury tabs could be as detailed as having a different tab for Disciples of Magic, War, Hand, and Land, or simply combat and non-combat.
If it is really necessary, the size of each of the armoury tab could be reduced a little, but overall it would still be important to allow some extra space through the armoury tabs (since you would effectively have multiple armoury chests).
Inventory
Have a quest where players with a level 60 class/job (doesn't have to be combat) can increase their inventory space by an extra slot. The details aren't too important to discuss at a suggestion, but I think it's important to allow players the opportunity to expand their inventory. We can do this on so many other MMORPGs, and it's very important this MMORPG in particular with the access we have to everything.
