This is another situation where I remain firmly in the "don't like it? Don't use it" camp. Why does it matter what other people do in their games?
Although it's not a facility I use often, I think I'd be somewhat irked if it became artificially inconvenient to use in case someone "abused" it.
Also I agree with this, wtf they care how do I play my game, I remember how I was irritated in HoMM when you had to pay for your hero to get permission to retreat with remained army.
This is not competitive game this is cooperative game, if I decide with my friends that we wanna "sneak in kill one and retreat" without fighting with others that are in area, why would we get punished for that???
That is
OUR decision in OUR game other players have no interests in it. Why would they cared how we play our games???
