The onliest issue I have with the current system are the paid retainers.

People that are paying for all 6 additional retainers do have the amount of market board slots growing up to 400% compared to regular players.

Every day I'm storing alot of items, because I'm at the limit of my market board slots with my two retainers. Till I get the space to sell the stored items, many times the prices dropped alot. So people with additional retainers do alot more money than me, because they have much more room to sell items the same time.

In my eyes this is an advantage that should not be there in a pay to play game.
