Another point of clarification.

I think the toggle prompt should be removed. As it is now, it's an extra button press while casting and I can see it might screw up your rhythm. I think toggle functionality should stay in.

The post Renta links to hits the nail on the head. Here's what I, as a pro-toggler, want:
  • "Z" will always toggle at any time, not just mid-targeting
  • A visual icon indicating whether AoE or ST
  • A visual overlay of what the area of effect actually is, such as a wireframe or glowbox plus secondary arrows indicating who will be hit.
I still stand by my earlier suggestion. Also, for those who are adamantly against anything that makes the game easier, put in a menu option to completely disable toggles, to remove the overlay, and to make it all a matter of guesswork once again.

I do find it troubling that the poll is split down the middle. It's disappointing that, despite all the alternatives provided, S-E has chosen to rob Peter to pay Paul.
