Improve cone attack damage

[Alpha-One]

I tend to skip most cone attacks, both melee and ranged, as they seem to draw more endurance than they're worth for the damage they do. While they can be great if you can get your position right, the way the game sequences the attack animation and damage vs the target's movement makes it rarely worth trying to reposition. One idea I had to improve cones would be to have their damage be inversely proportional to the number of targets hit. So a Heavy Burst into one target will apply all the damage to that one target while hitting multiple targets splits that damage up. It would be more "realistic" and particularly make cone attacks more effective vs AVs and such where there isn't always other targets to hit.
