On the other hand stevie, this is like the DBM battles at the club back in the day where my Palmyrans broke due to the loss of BW(I) (speed bumps for heavy cavalry) with nary a cataphract biting the dust.
If the losses were confined to those poor HD elements how likely is it that the regulars are going to shrug and fight on?
Perhaps the riders would say, "Look at all those dead poor people. Who will clean up the horse dung? Let's go home."
