They had more... there was a 475 cost mana regen aura (Mana Manipulator), a small health regen aura item (Emblem of Valor), and I believe Aegis has been changed what feels like a dozen times at least...Innervating Locket (health and mana regen), Soul Shroud (CDR and mana regen), WOTA used to have a spell vamp aura, and Runic Bulwark.
Riot's been on a trend of removing auras, not adding them. Probably because it's hard to balance them. They either end up being incredibly under-costed (old Aegis of the Legion was incredibly gold-efficient, even if you were by yourself) or very over-costed (current Zeke's Herald is over-costed currently, especially on supports who usually use zero of the stats and are already CDR-capped).
