I shoulda clarified, "bring a THF or /THF"

Why should BST have the same level of TH as a THF? You still have your ridiculous amount of pet melee damage, as well as your own damage, so you still have a faster killspeed then THF/DNC. And since it's not an all out "remove TH", you still get some coins

And yes, subbing THF will mean you lose out on DNC procs and dual wield. The idea is you pick one.
