So empowered seems to be in use on one or more of the plunderstorm abilities, which makes sense now, hopefully this is the only planned use of it as many people agree it wouldn't be great for most classes generally
I hope they do. The charged up Mana Sphere in Plunderstorm is way more awesome to cast than the instant Arcane Orb in retail. But it really has to have an impactful reason to charge a spell for that long. In my example the increase aoe size would be near meaningless in keys as pulls aren't so spread out.
