It has already been said in the merc thread that Kenny doesn't have any cures. It is also well known that shaman mercs suck at curing. I have gone several hours with only a handful of cures. Most of the time I have to carry my own pots just so I can move after being pinned. Best way to keep plat is to suspend merc and open chest. I am still waiting for The Great Mercenary Patch of 2012 that fixes paladin merc healing, and shaman merc not curing.
