Right now CC in PVE is bordering on worthless as it has recharge durations that are 10 times longer than the effect durations themselves. This means that nobody can bring enough CC to a fight, especially one involving high number of mobs, to allow any semblance of control over the fight.
End result is that every fight becomes a DPS race between the characters and the mobs, because attempting anything else is a exercise in futility.
The idea of CC as interrupts against other characters and boss grade mobs are fine, but that can’t be their only consideration.
