Uhm.... Pretty much any log has Rend Flesh/Melee damage as the highest two, Overwhelm itself isn't scary, it's debuff is, and cocophony is pretty much at the bottom for tanks along with Barreling impact.

You are right about the Bleed being more evenly spread that I thought, Warcraftlogs has an interesting bug or something where if you load into the damage taken page (like that link should do for you), you have to go to a different tab, and then back to damage taken for it to apply things like warriors or DKs absorb, some logs look really skewed until you do that.
The log I posted shows the DH taking almost twice as much rend flesh and melee, until you swap tabs and back, then they both look pretty much even.
