Looking for a tank/healer class similar to the Keeper profession in Anarchy online where they cast an aura that lasts several hours. You don't heal directly. The aura heals all teammates around every 20 seconds depending on the aura. A class that has a spell similar to this http://auno.org/ao/db.php?id=210528
There is nothing in eq2 with passive heals like you seem to be talking about. There are classes that proc heals when you do things, but it still requires active efforts to do the healing.
Inquisitors get a similar skill in that its cast and will pulse a heal to group members and has spells that fit that theme of healing (imo) but as said you will need to cast skills still. http://eq2.wikia.com/wiki/Inquisition http://eq2.wikia.com/wiki/Category:Inquisitor
