Replenishing your fleet prior to the boss node does help wipe away the ammo penalty which does make a big difference. I was talking more real-world stuff there. Support craft like oilers travel with the fleet and well before the main body of the fleet moves out to get into position, they get topped off. The way they must be used in-game does not make sense in this regard (hence why my comment was worded as such).

The way they have to be used in-game is that they take up a ship-slot that would be better served going to someone who can take a hit and/or bring firepower (Oilers do neither of these). Further, because they have frail armor, they tend to be taiha magnets.

This said, it was Hayasui that saved my butt in E4 and allowed me to complete it on Medium, though I had to pull 2nd Flagship shenannigans to do it because, again, taiha magnet.
