well, i know what you mean.
but self restricting is something a bit different to "not being able".
and since it wouldn't hurt you if they get the option, why be against it?
it's a simple boolean variable represented by a checkbox. nothing that would take up hours of the developers time... trust me, they worked with booleans before
as much as i dislike some of the changes... or better BECAUSE i dislike some of them, i'm all for making toggles so everyone can have a game that he enjoys to the max.
instead of shouting at each other and claiming that only the own way of playing is the "true" one... why not work together to make it a better game for everyone?
it's not multiplayer... it doesn't hurt my game if someone else has a different way to enjoy it.
