This is not true. This is why your calculations are incorrect.
Now if you are saying to minimize the amount of clicking you have to do so you can play more
ergonomically, then fine.
But the wolfhound for the second phase of WM fight is the best weapon.
(With the small caveat that the VBI Ranger actually has better sustained crit dps but a limited ammo pool and harder to shoot while on the run).
Just trying to spread the word that people should be using wolfhounds for the second stage so people are prepared when the total number of allowed into the instance is capped at 24 again.
Back on topic, I wish I had a boomslang to show the OP but I do not. Does anyone have the stats of a Boomslang at 5900?
