Personally I prefer the current healer roles. Depending upon the healer that the select, it can be a very strong support job, and if we we are discussing FL, if you are in a party with a different healer, then you can support each other quite well. You can combine potentially strong LB, CC and damage to both support your party, protect yourself and get kills and that is fun for me.
As others have pointed out, every job has defensive skills as well as some healing ability now as well as some extremely high DR in some cases. In addition, in PVP, sometimes people will just die, due to a lack of situational awareness, being out of range, are off off on their own, etc.
