We've got two house types - Bog with herb plots and Everywhere Else with crop gardens.
Crops can be bought at produce vendors but herbs can only be bought from other players directly or at auction. Wouldn't it be "fairer" if the produce from both types of garden were only available from other players? Even the seeds are available in an unbalanced way - crops from gardening vendors and herbs from the Ancestral Lands if you're lucky.
I'd like to see swapping arrangements spring up with bog dwellers getting their crops from friends in return for herbs.
I know every player would like to be able to grow both crop types but an interesting dynamic would emerge if players had to follow separate paths and cooperate to complete quests etc.
