Once per battle seems like an easy way to circumnavigate this. In reality, all heavy healing spells need some sort of diminishing returns for being spammed or per-battle limits -- PR's are far from the only perpetrator, just the most accessible one. Healing in general should probably be addressed by the next few patches, as any group that has several tanky healers will (almost) always wipe the floor with anyone who doesn't. Additionally, very few PvE encounters pose a threat when healing is as easy as it is now. I certainly know Seto could never come close to dealing more damage than Graft alone can patch up.
