Old Bold Knight, why stand and shoot? Possibly because you've fired for 2-3 turns at your opponent, maybe 1 at s4 15" range, whilst falling back. It's turn 4 and you're on the table edge. You're either off the table or maybe you get another s4 shot in and just maybe cause some wounds in hand to hand. Also if you're not on the table edge and this is happening turn 2, I would ask "Why?!" Fleeing foot archers can easily get caught by a charge from 15" away. I'd rather have more shots at 30" s3 than close range s4.
It depends entirely on the circumstances of course. One says shoot at 15", one says flee. Judge each situation by merit I say. I try not to let my opponent get to my bow line before turn 4, and still that's not enough firing. With their own fast cav, flyers and missile troops,
WE are on the back foot and reacting all the time, not dictating the pace. You can only do that with Glade Riders.
