If conjuring your familiar were put on a 10-minute cooldown instead of being a 1/day ability, it would help out with a little quality of life for those who RP with them. I'm not entirely certain how it might affect abusing familiars from a mechanical standpoint, but by my count approximately 0% of all spellcasters use them for combat outside of very early levels so I don't think it'd be too unbalancing. Heck, you could make the familiar cooldown a perk of reaching epic spellcaster levels to counteract that.
