Mass Cure vs Prayer of Cure

[chronologic03]

What exactly is the difference between these?
Does Mass Cure allow me to cure those in a different area as well?

[iloveyouxx]

Mass cure can heal BOTH people in the party, and non-party in a short range. (Like next to you)
Prayer cure, only heal people in the party.
Note: After patch on 7/28/2014, they made some type of mistake that, when you see the party members, but they are far away, and the others are close to you,
they won't be able to receives the heal.
