Shockwave vs. Thunder Clap
Shockwave is technically a ranged attack, like a hunter shot. This means it's treated like an attack (and not a spell) for purposes of what you want but can't be dodged or parried. (I believe ranged attacks can be blocked, but I can't honestly remember off the top of my head.) The Shockwave treatment might be the right way to go for Thunder Clap. Thunder Clap is currently a spell that hits for physical damage and can't be dispelled. The distinction among spell, melee and ranged attack (or persistent auras like Consecrate) is a largely technical one that doesn't always encompass unusual abilities well. (Source)

Thunder Clap in 3.3.3
I think we're likely to make Thunder Clap a ranged attack (like Shockwave) for 3.3.3. This will let it get 200% crits among other things.

Standard no promises, in case there ends up being a problem with that implementation.
