I don't miss draconic presence because its not scary, its mechanics trying to simulate your PC being afraid but failing to touch the Player.
DM: You're stunned
PC: *yawn*
DM: because of the scary magnificence of the dragon! Its scary!
PC: Hmmm? Oh I heard you, I'm still stunned, right? *yawn*.
Now its:
DM: The dragon bites you, you're taking 25 ongoing damage until you escape his mouth because you had the audacity to bloody him. You strongly suspect next turn he'll breath fire....with you in his mouth.
PC: Yikes!
If you want to simulate how scary a dragon is, make sure his powers scare the Player, not the PC.
