Yeah, both CNJ and WHM are severely limited in support abilities. There's not a lot of variation. It's just Cure -> Cure II.
Maybe it's because I came from XI, where a typical rotation included Haste, Barspells, Debuffs, Regens, alongside the cures that I find the healing classes lacking here.
Well, personally I felt XI went bonkers with spells. You hardly used barspells and outside of Prot/Shell/Haste everything else seemed extraneous. You have an Erase, a single target heal, an AOE heal and a HoT for WHM. You're getting the other half of your buffs from BRD. The reason why you don't have a gaggle of spells is that as you level those spells improve.
This is just my personal opinion but I dont think an overabundance of spells necessarily lead to increased complexity or strategy. I think they're streamlining the abilities so that you have what you need for any give situation rather than having spells you might use once a week.
Also, you're not going to see alot of options right now because CNJ abilities are limited to the level 30 class skills and nobody knows the new job specific skills because those quest lines are locked too. The data mine is only as current as the beta client. Those of us who have jobs at 50 are limited to the old skills they decided to keep, it's not our whole toolset yet. Until we get to phase 4 and a complete client, its anybody's guess.
