Why is the healer class basically a one spell dps class?

[Anhra]

Instead of more Dps skills give healers more utility skills, reduce damage, increase dps,spells or skillspeed. Make ranged full dps and give their buffs + old Ast cards all healers.

As things currently stand, Healers have way too many raw healing abilities (14-18, iirc). A CNJ alone with cure1&2, as well as medica 1 (and rescue) are already enough raw healing potential to cover EVERY Dungeon this game has to offer. If those Skills could be reworked in a way that it works in savage raids as well (lets say were being generous and keep 1-2 Healing Spells from the ones i havent mentioned), it would leave us with 9 "empty slots" on average which should be more than enough room to give healers both the utilities and dps skills they actually deserve.
