When the playerbase and the imms fundamentally disagree on issues that are part of what the imms consider game-balance or long-term direction of CF, for example putting haste back in the game, or allowing spam practicing defenses against kobolds prior to level 11, virtually never.

Good ideas that don't have any effect on game balance, and add to the enjoyment of the game, I'd say fairly often.

The hunt was moved to a level 42 sup, the outfit command was put in, newbies without shield block now potentially have two options available to them (polished buckler or the academy seal). Newbies start out with a haversack and water container.

It might seem like the imms ignore the playerbase when they refuse to adopt changes that they feel simply alter what CF is or where they want to take it.
