MD + MCH sounds like the "independent adventurer/explorer" type to me. Buff yourself, buff your pets, let them do all the fighting and heal them. However, creature damage is pretty slow, so if you're the more impatient type, you may consider dropping some of the injury treatment line in favor of set of fighting skills (marksman). If you're a more proactive adventurer/explorer, than pistoleer/rifleman/carbinier is the way to go.

It all depends on what style of fighting you want to do and what you intend to do with your Master Doctorship. If you want to be an "invaluable member of a group" due to your Doctor skills, then MD + MCH as it stands is proably good enough. If you want to solo, you will probably need to do some fighting yourself.
