Losing 25% of my HP (36k in a group with str jewelry vs 48k with vit) makes a big difference. Sure for a polished team of people who played together for a while you can make that work. For average Joe in a random duty, that's 25% loss is to much.

What I see will happen is they will just lock out all HW jewelry with the upcoming patch to prevent using this. Might not agree with this completely, but that's the most logical path they will walk.
