Most S&B intim are going to be either DoS or Stalwart Defender - so what I suggest is this:
On the 2nd or 3rd tier of DoS and Stalwart Defender, in addition to what is already there, add this - every point that you are healed while holding a shield adds 1 point of threat. This, along with the new changes to intim, would help sword and board intims hold aggro when they need to the most.
Discuss.
