If Riser never had a bond with his servants, they wouldn't be so loyal to him. As to the bigger issue, just read my recent post from above.

Also Riser does view Rias as Rias, at least Riser's perverted self does, but back then Riser wouldn't say or show such things. Remember the Issei vs Riser round 2 thing, that was Riser's true self unhidden by his façade of being a High-class Devil from the Phenex Clan. Unfortunately for him, he was too late. ;) So we have Issei x Rias pairing which is a very good thing.
