Reduce, don't remove.
Why?
Tradepacking has always been the best source of income but it has the biggest limitation to it that is time.
You can't do anything for the time to earn the money, but the time to get the money is 22h which is a long wait. Those who need money instantly will sought to other methods which potentially gives them lesser money but faster.
If you remove the 22h duration, then this will become an instant method to make money.
Why I am against it becoming an instant method is because people will only do tradepacking and the crafting and other so occupations of the game will go useless which are necessary for the game.
I could be wrong of course and removing could still be good, but I am still +1 for reducing it to 4-8h or so.
