Just tried the new and improved Ritual of Souls, and it's great. It only takes your self to create it now, 3 second cast, and BAM, the little dispenser basin drops. Best thing about it, you can use it in combat! Not sure if this is intended or bugged, or net yet completely done developing, but for now we can provide our raid/pvp group with healthstones while we are in combat.
I also tried using Ritual of Summoning to see if that was a single cast now, but it still gave the old floating portal cirkel so my guess is (for now at least) no.
