The following are ideas that will Fix the banking problems without adding more bank space. It will ease the general population and Make wow players less likely to feel they need to horde items.
***Idea number 1) In each zone designate a pre-existing NPC to become a vender. This NPC will sell all items that are obtained thru questing in that zone. The items will be available for re-purchace if the player has previously completed that quest and is 10 levels above the required level for that gear. This should insure that the gear is only used for transmog. Jewlery and trinkets will not be sold by this vender, the vender will only carry vanity items and gear that can be transmoged. The price of the gear should be the amount the peice was sold for and the amount you got from the quest added together then doubled.
What this does: This will allow anyone who has ever saved a quested peice to delete it. The peice will now be saved for you on the vender. You will be allowed to re-purchace it at any time. This will allow all old players to re-purchace items that where deleted long before the idea of transmoging came. Each new expantion now comes out with a color story per zone and unique weaponary that is quest only, these venders will ensure banks do not get filled at the opening of each expantion.
***Idea Number 2) The lucky mojo vender. This vender will sell the following:
1) The mojo potion of armor: This Potion will only work when soloing, It will increase the drop rate of your armor type by 30 percent.
2) The Mojo Potion of weapons: This potion will only work when soloing, it will increase the drop rate of all available weapons by 30 percent.
3) The Mojo cauldren of the blingless: This will exclude all rings, necklaces and trinkets from the loot list of any raid 10 levels below you.
What this does: It allows you to re-farm older sets in less time. This will free people to delete these sets from their bank. As new armor is made and added the older less time consumeing items to farm can now be deleted with relive ease that they can be re-obtained quickly.
***Idea Number 3) Utilizeing The Black market auction house. Use this to sell Transmoging items that have been removed from the loot tables. NOT only teir 3. The priceing should now be 5 grand or below and should include the following items.
1) The missing belt and boots to the teir 4 pvp look alike armor.
2) All frost armor peices from the old naxx raid, with focus on the gloves and legs.
3) No longer obtainable pvp armor color waves.
4) Random peices of vanilla gear that are currenly only available to NPC's.
5) The Belts and boots to all LK pvp gear. They can drop in VoA but have drop rates so low they require a 2nd source.
What this does: this takes a now useless NPC and makes you want to visit her. This allows people to complete sets. Ideally Blizzard should take all items it removes from the general loot table and randomly funnel them to here. If blizzard is good about this the community will be eased and no longer hold on to these items as tightly because there now is a way they can re-obtain them.
***Idea Number 4) Make all Holiday items Bind to account. These items have a rare drop rate and usually only drop for alts that can not use them. Haveing to sell a item you want on another toon is not a prize its a annoyance. We already get annoyed enough by real holidays WoW should be kinder.
What this does: This makes us look forward to a holiday. This allows us to channel our holiday items to alts who are drowning in bank space.
***Idea Number 5) Vanity items with a effect should be removed from inventorys and place into a account wide system that resembles the system mounts and pets are currently under.
What this does: It allows all your char's to utilize these cool little things that make the game fun. It Also free's up bag space for several people.
***Idea Number 6) Make Food and Most materials stackable to 100.
These 6 ideas if Added to the game should allow the influx of new gear without calling for more bank space season after season. Any player who is practical with what they save should be able to have enough available bank space to fill their needs. Currently As this game stands the storage space is not expanding with the incoming items. Older Players are suffering the most by this, usually getting called hoarders every time they do ask for more space.
*** As a bonus I think that Players should recieve a bank slot for every year they have been playing as a reward for costumer loyalty. If you put ideas 1-6 into effect they will most likely not need it but regardless it would be a kind gesture to the community that supports you.
Take a look thru your mains bank space now and see how much room this will get for you. You would be surpized. Also if you have Mogit, Take a look and see how many new outfits this will get for you. :P
