Generals are indeed very hard to kill. Also, do the spears work correctly? I have had my pontic general unit 60 or so strong crash head-on into a full pantodapoi spearmen (not phalangites) unit and after fighting it out for 3 minutes on the spot, I routed them without really losing more than 15 horsemen. I mean, the stats of the pontic general aren't really impressive either and with the reduction in HP I would have expected my unit to disolve in seconds (it was more of a diversion charge and I intended to pull back immediately, but found out there was no reason to!) at least from my experience of RTRPE so far...
