Sorry the build is terrible, you skip over some of our best threat abilities - I would not normally advocate skipping certain core talents however if you absolutely do not need them (ie you never need healing) then I would go with something like this:

(chosen not to take spiritual attunement as you are not getting healed)

BTW you should not be having threat problems unless your tank is severly undergeared. You may want to post your paladin macro so we can see if that is where your problem lies (ie if highest threat abilities are being used first)

Another trick I like to use is to pull with hand of reckoning and use Avengers shield when the mob is running towards you. This way you get 2 instant ranged damaging attacks so your other dps should not be able to pull off you.
