if you buy a game and are satisfied with what you bought why not enhance the product for a reasonable price?
Small DLCs as we now them from certain companies are a (quite efficient) instrument of profit maximization, not of enhancing the product. Small improvements to the product should be considered service and thanks for buying it and not destroy its unity by making additional pieces exclusive to pay-willing people. Bigger improvements and additions that require a higher amount of resource investment for developers/publishers should be sold as once so called Add-Ons or Expansions to a fair price. There is absolutely no reason (but greed for profit or, in a few cases, existential threat) to SELL small DLCs.
