I don't think the spearmen will charge the Reiksguard. If they do and make the long charge it would pull their wizards out of the ruins bubble, losing the bonuses for casting, dispelling, and the xtra 100 vp's for most wizard levels within 6 inches of the ruins. They might try it but to net gain appx. 100 vp's after giving up the 100 vp's by moving out and giving it to us if our wiz moves into the bubble, I wouldn't. He would have to make the long charge, win the combat, break the stubborn Reiks, then run them down and they are swiftstride.
