Refresh me please (traps?)Follow

First of all I apologize I took an extended break from wow and forgot a couple things.

There was some little piece of knowledge in my head about the patch that kept saying something about a move that refreshed the duration of immolation trap. I don't know where it came from but my head established a shot rotation something like this

Trap Launcher -> Immolation Trap -> Serphent Sting -> Explosive shot -> Aimed Shot -> Steady Shot -> Steady Shot -> ???

And repeat except when your your traps were off cooldown immolation trap would be replaced with black arrow, and ??? was the move that would refresh the duration of immolation trap...

Does anyone know what ??? might be? Maybe I'm just crazy.

Thanks for any help

It would have been perfect to have a 41 pointer that read:



This would have allowed for a true skill check, because glyph of immolation trap reduces it's durationg by 6 seconds (to 9 seconds) and increases it's damage dealt by 100%.
It would have been the single best dps glyph available, but you'd have to ask yourself if you think you're capable of always under any circumstance firing an explosive shot within 3 seconds of it coming off cooldown.

It would have yielded the same amount of dps we get from black arrow now, only without the clunky last minute fix feel that BA has and it would have given us something that fits much better thematically.
