Well, i am assuming you travelled with these as your companion, while playing....yes? if so, i would like to know how you managed to level up without the healer companions healing you, because i find it next to impossible.
Though your description does look cool for roleplayers.
If you are a healer then most likely you don't use the healer companion. i know I dont' on my sage but I do use my healer on my Shadow so it would depend on your advanced class.
