I know that my Assassin and my buddies Marauder at 13 did the Black Talon FP with a our friend on a lvl 10 Merc and his Companion healed it. Not sure if that type of deal would work in later levels though.
Downside to that is BT is a 2 man FP. Having three people with a healing comp was overkill.
I was able to solo all but the final boss on a level 12 Sorc with my companion tank in beta.
