In the original Everquest this was typically an enchanter who could lock down mobs, with pulls being intentionally designed so in order to win you'd have to lock down so many members of each group, keep them locked down, and fight the group in a specific order. This continued into WoW to an extent where certain classes would have spells like Polymorph (the sheep O' legend) to do the same thing, and you had specific classes able to lock down specific types of mobs. Depending on group content you could wind up doing different fights very differently depending on what CCs you had in the party.
At any way MMOs moved away from that and in over a decade now I guess I don't think there has been any real expectation of routinely using CC, never mind having a class built specifically to facilitate that. I do remember in very old school Molten Core playing as a mage and having my main job being to keep specific mobs polymorphed, more so than DPS (that and the almighty decurse spell needed to deal with certain boss mechanics). Today I think things are actually a lot easier in a lot of MMOs (even if I am slowing down) as people can more often tunnel vision, and typically just focus on rotation, a bit of movement, and whatever mechanics a boss might have in a certain phase.
