well. there's sense there..there's no reason those riders would be better than any other 'elite' cavalry.

but it would certainly increase the "killability" of a general. maybe not versus the ai, but I'd definatly sacrifice a unit of companions/hetairoi to kill a general(read=run aroudn teh line's for a quick kill in MP)if a generals bodyguard is weakened, it will definatly be easier to kill teh general..but than, the general unit is not meant for flanking...except your Alexandros..
