At some point you've got to ask yourself: "Am I willing to play in a way that supports my party?"
You started your post as if you cared about the load you placed on your healer by checking their gear, but complained at the end about the healer who wanted a higher heal check.
Tank is a fairly supportive role. If you arent willing to support your party, maybe it's a good idea to change to a less supportive role.
