So we want to replace dilligence with flashing lights?
In the real war, there were people who were tasked with spotting the enemy.
Using that logic you may as well turn off base flashing all together. But, base flashing is the AI spotters who are supposed to be on the lookout for an incoming attack. Again... my point is, if they can spot a plane or a jeep, they should be able to spot a task force.
Many players are diligent as well. But if a base is not flashing, and the dar is not down, there are many other things that can get our attention first. Hence the reason the base alerts exist in the first place.
Remember also that none of the countries is fully incapable of actually bringing a ship to a base without someone upping from it to drop a single bomb, die, and move on now that the enemy has been alerted and is on the way to destroy the ship.
In some cases yes... and that would be true for the most part in LW, as there are a good number of players who dont know each other on the same side, dont listen to direction, or simply dont care. In MW or EW you have more of a chance to pull it off though, as the team is smaller, and for the most part, knows each other and will work together in doing this.
But I have seen it done even in LW too.
Again... its a matter of:
