It would have been bad implementation if it wasn't a bug.
If we were to assume it WASN'T a bug, then the idea would be that we are balanced around rebuking every 10sec for the extra damage. This in turn would mean that Rebuke isn't a choice talent but required to reach our balanced DPS. It also means we can't use Rebuke as an actual interrupt as it's part of our DPS rotation and delaying it would mean a reduction in our dps.
It's the same line of reasoning why blizzard ended up changing how HoR worked compared to initial implementation and only make it do damage when the target is actually tauntable.
Following the same line of reasoning, you can also infer that the Censure DoT ticking speed is a bug. With some nifty seal twisting and proc watching you could end up having haste make a serious change in DPS done, this can't possibly be intended.
-> Start with SoR, pop a speed pot prior to the pull, judge for the haste buff, wait for a haste trinket proc (hope it procs before speed pot runs out), and only if all of the right things happen start wth SoT to have Censure ticking at the fastest possible speed for the entire duration of the fight (asuming you can keep it going). You can probably even find some more stuff to add onto this for even more (temporary) haste that then keeps being applied.
Edit: You could even use the level 60 BWL pala trinket (
Scrolls of Blinding Light - Item - World of Warcraft) which has an OnUse haste proc (I'm not sure if there's newer/better ones with an onuse haste) prior to the pull and swap to a better trinket for the rest. This isn't the sort of things blizzard tend to like. Expect a change, though it may take them a while.
Edit2: have a backup weapon, enchanted with black magic, use that on the pull and hope it procs before the speedpot and onuse trinket runs out.
