Any feature that has to be selectively disabled in specific places is a feature that should not be implemented.
Game Design 101
Consistency is mandatory.
Either you enable a feature everywhere, or you don’t implement it at all. Selective enabling/disabling is disgusting and is game design failure by definition.
That is complete BS. I’ve been gaming my whole life and tons of games selectively take features away for certain areas. Single player games usually wrap it in a story element, but it is still there. There are areas in WoW you can’t ride a mount, how is that any different?
