Consecrate, Divine Storm, Judgement, wait 3 seconds, Divine Storm, Judgement, repeat.
Did you see it? Three seconds of nothing to do. The problem with Paladin AoE DPS is that we're stuck with just sitting there waiting on a cooldown while our DPS goes down during that three seconds.
Here's what I'm thinking: Give Divine Storm a greater chance to give us one Holy Power. Make it a separate talent, change the mechanic, I don't really care. My DPS is fine as is but that wait is painful.
