I'd argue it's probably outdated debate. The reality is that it would take a notable investment in STR to even equal +1 damage from healing on things like Bloodbath; by comparison you get more consistently relevant chunks of HP through Vitality (which you also get 25% more of due to Defiance).

The only way I'd argue it is if you plan to spend a whole lot of time in PvP, because there tank classes want to swap their VIT accessories for STR anyway; but that's sort of sideways to the main objective of the class in any other situation.
