You're assuming folks have the time to spend 2 hours LOOKING for the fleets and another 45 minutes getting the attack package to them after that.
The point of FSO is to engage the enemy. Not to re-create gameplay best suited for offline games.
Even with "target must be hit by T+60" many times strike packages barely find the CV and get within visual range by the alotted time, let alone having any escorts, top cover, or beneficial positions. Often times we've got there by the skin of our teeth and had to dive right in. The results of such hasty attacks are usually dismal.
Forget the whole "we need scout missions!!!" requests we've been seeing for years, they don't work in online games where other folks sit in the tower 2 hours for you to do a 1-man job by yourself.
