Rest of the time you circled through combustion/Incinerate or used Shadowbolt, depends on Patch.
Oh, and it was optimal to stand in melee for shadowflame damage (which is also a kind of DoT).
And your cooldown buffed 3 spells every 2 minutes.
So I'd argue that Cata Destruction was in fact NOT a nuking spec at all, because your damage was divided between your Pet, DoTs and filler Spell, you had no nuke spell at all, besides Soulfire to keep up a damage buff every 20 seconds.
OT: Even IF shadowbolt returns for Destruction, there won't be a mechanical difference. Both are just filler spells with different visuals, it won't change your gameplay at all.
