I am with you. I also never came across one. However, I am playing the game for shorter time. I have started playing about two months ago. I share your opinion that the healer classes are very important part of every RP games, such as Vanguard. In addition, if there are no healers in the game, the developers had a good reason for that. I believe in them, and I believe that all of little mistakes would be fixed in the add-ons and expansions in the future. I have heard that a major one is coming out soon. I just cannot wait for it.
