Just for the record:
Personally I don't
need it at 1 hour, though I would welcome it. Four or even (with gnashing teeth) six hours would do. That would help me jumping to the ganged side in the noon, because can make another decision in the evening again.
Oh and another word on the spiez... while we "high profile" players are constantly being monitored by distrustful eyes, the real ones will hardly be noticed, for they are silent and anonymous and most of the times not even side switching at all. You can up the limit to a month and they will still be there
(Maybe now someone will come up again with "disable cross country communication"
)
Finally: I actually
would be contend with a very long time limit, like once per tour... if the MA really were a "war arena".
