I don't know if it is intended, but geticoi stratiotay pikemen and komatay stratiotay pikemen don't have bonus melee defence when entering in phalanx like the rest of phalangites....when starting campaing you have four generals with ktistai bodyguard, new general don't have ktistai as availble bodyguard unit. I think ktistai as bodyguard should be availbale from begining. Still I think that dacian heavy skirmishers (comatai) should be availbale from begining, without reform because in their description is written that they form main body of dacian tribal armies, so they should be a starting unit.
