Comment 3 for bug 550761

Meanwhile I have also seen enemy buildings burn down, because I had manned a military site.
I have not seen the actual border move when this happened.
IMO this is not the behavior that WL showed prior to rc2.
Borders in WL have up to now always been depending on conquering enemy territory, not
on guarding your own. (except of course when progressing into unclaimed territory)
This has always been a major difference to Settlers, where borders changed all the time.
So I think something has changed here.
I wanted to point that out, because I dont not know whether this was a volontary change.

Yes, it does make sense - and I'm neither pro, nor against the change -- merely surprised.
