What does it take to create new powersets?

I think activation is more a factor for balancing than strength, as is animation time and redraw.

The lower those are the faster you can spam them in combat. My favorite blast set, dual pistols, was getting shorter animation times in I24. It was already a fine set in my view and this would only have helped.

It was these little tweaks in balancing that the Devs did that really showed a global view. They were willing to try and balance all powers and sets on a global basis and risk player rage if need be. That is a delicate act of juggling that I don't think can be done easily by players or modders. It's easy to make a broken set but damn hard to make one that doesn't unbalance the game when it becomes FOTM.
