It was a good ise be4 when players blocked off the map, not amymore. Yes to have some kinde off radom moving around NPC´s sounds fun in contrast to hte today standard static map when you know what will happen (if no other player interfer) and will create some radomness and to have a defens at home and not only in the purge gauntlet. Yes in a way we need abit more danger in the game (its a survivle game) but not a total base leveling whave of units, spec when its mostly hurts the soloplayers most.
