Having done some extensive testing with mercenary healer, i'm genuinely concerned about some of the limitations its going to find in play

There are some key items that need to be reviewed
two of the skills that are commonly used in the builds today are not available for selection choices

these are:
Jet rebounder from masterful (cd when hit and small aoe heal, plus heat management properties)
Stabilized Armor from Heroic (30% dmg reduction while stunned and 30% reduction from all aoe's) Which in particular is going to hurt any pvp prospect for mercenary healer
