I played both Jedi Shadow & Sith Sorcerer in 50 ranked WZs. Overload and Force Wave is so useful that it should not be 120-degree cone in front of player. If 360-degree is too large of a radians, is it possible to make it 240-degree instead of 120-degree?
I think the main thing the Devs are going for, is not being able to hit players directly to you sides. Anything greater than that 120 would hit those players. They seem to want a new mechanic for the way consulars/inquisitors use their KB.
