What BB fail to realize when they change things is all the time (and money for some) invested by players is changed too, so no weapons in loot means players have to change how they do adventures, all books invested in specialists like finding that extra deposit like my geologist hasn't found for months is worthless too and causes players to get angry that they are no longer getting what was paid for / earned.
How can players give positive feedback when all the changes are negative for the players and the game?
