So, looking at numbers and adjusting in the aimed shot in half not shooting at the dummy. I am trying to figure out why you would fire Marked Shot in any situation that doesn't include multi-target.
These are based off my numbers and normalized so that Autoshot is 1.0
Code:
Autoshot 1.0
Volley 1.57
Arcane Shot 2.1
Marked Shot 5.18
Call of The Hunter 2.39
Aimed Shot 0 6.08
Aimed Shot 1 13.08
Aimed Shot 2 13.99
Aimed Shot 3 14.91
Aimed Shot 4 15.82
Aimed Shot 5 16.73
Aimed Shot 6 17.65
Windburst 15.06
Multi-shot 0.69
Sidewinders 3.87
