More "Collectibles" options in bank
I was thinking about this same topic, but i have a suggestion that may make it a little more convenient for all those who do dungeons often. Instead of having the tokens in the form of an item, would it not be possible or practical to convert each one into there own form of currency such as gold, and how you deposit gold in the bank, this eliminates the problem of having to keep multiple stacks in the bank and on other characters.
Not sure if this would be easy to implement but being able to go to the bank and deposit 1000 COF tokens without messing up ones storage for other collectibles would probably make it a little more comfortable for all players saving for weapons and armor.
