I would not want more cure abilities thank you, just because many healers cannot play their job does not mean we need to sacrifice Red Mage as a dps and turn it into more of a healer...
Status removals like mentioned by Johny ^ is not a bad idea but that is so niche, how often does one have to use that anyhow? Granted i have never raided as a healer so dunno.
Besides they do have to be very careful should they add more healing abilities, because things must be balanced (even though casters never are)
Knowing how SE is the very much wanted job Dancer will probably be a dps with such things (healing and buffs, etc..)
