"That can be modded in later" is just a totally worthless reply. You can use that reply to dismiss a huge range of bugs, cut features, game breakers and shortcomings that should have been sorted out and it's really just the equivalent of burying your head in the sand.

If you don't like these hypothetical sliders, you could always just....not touch them. That way all you torch wielding peasants who fear change can remain blissfully ignorant with the default settings, while the rest of us who don't like the silly arcade fast battles of the last few TW games can slow things down to a "realistic" pace, more like STW and MTW.
