Personally I love the gameplay healers had during 3.0 up until the end of 4.x. There was something rewarding about balancing out healing, supporting and DPSing. If you're good at balancing both heals and DPS and keeping the party alive to the best of your abilities, you're a good healer. If you focus too much on DPS or if you keep healing and then just stand when there's nothing else to do, that makes you a bad healer.

Now that they're all "streamlined", it just doesn't work. Healing is too easy now with the added skills/abilities and DPSing is now boring for having less. Your means of support was also simplified. There's not much tactical decisions involved in AST and SCH anymore.

I really don't get it either. The fights in this game isn't exactly designed for healers to constantly keep on healing. The devs said they're making healing much harder now or make healing more of the focus, but the exact opposite happened while making every other aspect in healers became boring and unenjoyable. The healer role is just terribly designed right now.
