nah dude, this is way too carebear. At best, build a sissy server where it's Players vs. Barbs. meh.

Your suggestion only teaches kids that when the going gets tough they can bail at any time into a warm and fuzzy safety net. This is a game of war, not a game where "I don't want to be attacked so I'm going into 3day protection".

If you can't take the heat, get out of the kitchen... or better yet, don't even bother showing up.
