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

[Kabooa]

CC did have a place for a very very short time in early ARR dungeons, then SE nerfed them into the ground because people kept complaining about the difficulty and it simply became "pull everything and aoe it down" and consequently crowd control lost it's purpose.

CC got removed because people were sleep-gating mobs. That in turn evolved into the standard two pack gates we see now.
