I agree with the OP 100%.

Bringing interrupts like WoW also brings more skill to the table too. Mindlessly hitting someone on bard to interrupt them 100% of the time is too easy. Timing a Blunt Shot when the enemy surecasts takes some thought at least.

Every DPS should have a form of interrupt. That on top of Stuns would be more than enough to still disrupt casters...interruption from damage is just broken as hell when the enemies abuse it (Putting a bard on each healer while melee just wreck everything else)
