I think the sort of player that is drawn to healer type builds are those that have player personalities to match that supportive and helpful roles such a character plays.
I love playing healers. I prefer to play non-religion-based ones, when possible, but I'm okay playing a cleric.
I have a sort of caretaker personality in real life, so that factors into my love of playing healers. I also don't GM or play rpgs as wargames - it's not all about combat or "winning" to me - so I enjoy roleplaying characters who bring value to the team outside of combat roles.
