The Ultimate Banker's Collection:

Rules: No level requirement higher than level 5 may be used, as most banker toons exist in the range of level 1-5. Items with no requirement at all are preferred. The higher quality item, the better, but quality should never trump style. Style is greater than all. Cost should be as high as possible, to show the influence of your Banker and ability to procure and sell items. But again, style trumps cost. Points for any class being able to equip the item. More points for improving your style as only your class can and no other, as this shows more prestige and elitism. Further points awarded for using as many item slots as possible on your toon.

The choice of the Tux Shirt or Formal Shirt is based on style, I prefer Formal myself. Looks better on female toons. The choices of The Rock or Tarnished Silver Ring hinges on whether you prefer to show off the money you throw around or the time you throw around. Frayed Gloves, Belt, and Shoes are throw-away items, place holding. They look good with the outfit, but don't add anything to your prestige. Skinning Knife is chosen because it's totally unbreakable! Which is key for a Bank Toon, who should never waste money on important things, only on useless things. That and because it has way more class than the other Unbreakable weapon, the Blacksmith Hammer.

The Off-Hand choices are mostly up to style. I prefer the option of the single red rose, however the black options have potential for some, especcially for Undead toons. The Bouquet of Black Roses is even more prestigous however, due to the hefty increase in cost. However, the Bouquet of Red Roses is clearly the king of prestige items, due to the fact it can be used at any level and it has a proc, but only obtained in high level instances. Making it very tricky for the level 1-5 bank alt to procure.

Suggestions on improving the list are welcomed and encouraged. Banker Toons of the World... UNITE!
