Buff Bot for Epics?

[dbik]

If I wanted to build a character on my wife's account that would sit at the quest entrance and buff me before I go and kill stuff...what build would you use?

Not talking about dual boxing...just a round of buffs at the beginning of each quest. I'm thinking primarily Heal over Time effects.

I realize bard is the obvious answer, but then I figured there is some low hanging fruit in the cleric trees as well, ones that aren't dependent on cleric level, but the heal skill instead. Even sustaining song isn't bard level dependent for the amount of the heal, only the duration of the heal.

With all the nuances and subtleties of this game, to include epic destinies AND twists, if you could build the perfect buff bot, what would you choose?

Any and all recommendations are appreciated!
