Slow to progress, I certainly can understand that, but when you drop in the middle, got your ass handled and have to load a previous save, wouldn't that slow you down as well? There are still people, who try taking on fortresses unprepared, rushing and so on. Forcing them to land in a safe spot, then taking on the enemies along with the shield generators would at least draw a clear line for some of those. People complain about the game being difficult and whatnot, this surely doesn't add to ease the difficulty much.
