Divinity.

[Spectrum]

Divinity is weak per point. Because of the way +%healing stacks vs mitigation it's really only as good as about 3% mitigation. For 5 points that isn't worth it in general if there are other good talents to pick up.

However, if you're still dying a lot you want all the help you can get, and that would mean picking up Divinity if you're not threat capping your DPS.

Divinity does help your survivability. It's just a really bad return per talent point.
