I love some of the ideas for the new powersets. But there's something bigger(and probably harder) that I'd rather see, and that's the ability to customize how a power looks.
For example, the ability to pick the size of your katana, or the number/shape/length of your claws, or the color of the flames my fire aura gives off, etc.
I would assume this would take a ton of resources, but man it'd be cool. And in my opinion you simply cannot do shields and have everyone using the same shield. Just wouldn't fit.
