after the lack of tank we have lack of healers now

Because they reduced their DPS ?

If DPS is so much important that reducing it kills your job, why didn't you play DPS from the beginning ?

IMO:
It's more than that.

On the dps side, SE simplified already simple rotations and removed stance dancing. This makes it difficult to feel 'skilled'. I've tried to make 'skilled' plays other ways. For example, maybe I don't heal someone immediately so that I can utilize a reduced CD from the lily system and continue to dps. But then a PLD or RDM heals the target before my CD is ready...

On the healing side, the healers feel less important. As mentioned, PLD/RDM may heal something messing with a plan you made in advance, but it doesn't stop there. Take esuna as a role skill only to have a non-healer remove a condition. Hit swiftcast for a res only to have a RDM insta-cast, etc.

It just doesn't feel as rewarding to play.
