Honestly your best option is to make all of the stats unique (including the health). Or disable it entirely until you can make a DOM version.
BC is pretty OP, but it's even worse on DOM because gold is so plentiful. A toned down, and unique stat version is probably the only way you're going to balance it properly for DOM.
Even with those adjustments you listed, it's still the BFT of physical damage. It offers way too much for the price. And as an extra note almost nothing on the item goes to waste if it is stacked. (That right there is the problem)
EDIT: Lawl funny how I get downvoted, yet all the more well known posters that said exactly what I suggested get upvoted. This community makes me laugh sometimes, in that said laugh of pity of course.
