Yeah, PWS was nerfed way too hard. It has a cooldown now, so I don't see why it absorbs for shit amounts.
All damage reduction CDs had their cooldowns increased. Blizz said they don't want us relying on them too much.
Mmhm, it hits like a wet noodle in 5mans; barely heals more than a Penance. It just leaves me thinking: "Seriously? This is our big, powerful artifact ability? Something that heals for 10-15% health on the group? What a ripoff."
Even holy's RNG-based one is way better, as it essentially gives you double healing for the next 15 seconds, and can proc repeatedly. Light's Wrath is just horribly underpowered, for a 90 second CD. Either buff it, or reduce the cooldown.
In my experience, it doesn't target people who are missing health, it targets people who are missing Atonement.
But yeah, the awkwardness of PWR targeting is one of my bigger gripes with Disc. Really needs some fine tuning.
