I looked up a few top 10m palys and I noticed that the majority of them use Light's Hammer instead of Holy Prism.
Now, looking at light's hammer, it has a ~26% up-time where as Holy Prism can heal 5 people every 20 seconds.
Could someone tell me why they're using LH instead of HP? I'm guessing because it hits EVERYONE instead of just 6...but I'm not sure if it's worth using because of the 74% downtime...
I heal a 10m group and we're only 3/6 Heroic, but I find the ability to use Holy Prism every 20 seconds to be REALLY useful (plus it almost replaces my WANT to cast judge).
