A reliable interrupt is one that is off the GCD, and on a 10-15 second CD. Kick, Mind Freeze, Pummel, Shield Bash, Wind Shear, rebuke, are all reliable interrupts. HoJ is on the GCD with a one minute CD. For fights where interrupts are key, it is typically a 2.0-2.5 second cast. If you hit a spell right before the cast begins, you're looking at only a 500 ms window to actually get the interrupt off. That's unreasonable.

Vindication only affects the primary target of Hotr on Beta. Only one target. DKs can pestilence, and Warriors and Druids can demo, and get all the mobs attacking them, while paladins will be taking much more damage.

And tanking CDs are extremely important in raid content. Being able to reliably chain many CDs made DKs by far the most effective tanks in T7 and T8 content, and only having one CD, despite it being the most powerful single tanking CD, cause paladins to be nearly useless on encounters like OS 3D, Vezax HM, Thorim HM, Mimiron HM, and Iron Council HM. There will always be encounters with massive Burst damage that needs to be mitigated with a CD rotation, and the tank that can provide their own CD each time, rather than taking up other players GCDs to provide externals will be favored in progression. It happened in BC, it happened in wrath, and it will happen in cataclysm.
