I never had "proof" that the WF can out do other higher DPS weapons (other than my own math that is) until a couple months back when someone (Worx I think) with a DPS meter was in my game. At the time I was 210K sheet DPS with a Manticore, and their DPS meter said that my eDPS was ~600K. I swapped out for the Windforce and 150K sheet DPS, changing Caltrops JS for Gloom and Brooding for Vengeance. With this setup the meter said my eDPS was ~1450K. I lost ~30% sheet DPS and gained ~115% eDPS. Not the 2-3M eDPS a 150K WD or Barb puts out, but none too shabby either. It might be that high if I worked Choking Gas into it, but that extra 0.5s for LF is crucial in HC.
I have a pretty decent WindForce, but when I equip it I lose about ~70k sheet dps. I do love playing with it with sentries, but I'm curious what combination of skills you used to actually get more eDPS using it. It seems like the sheet loss is just too massive. I wouldn't even care about actually matching the Manticore, but would love to hear some ideas on how to use the WindForce better (easily my favorite weapon when playing solo.)
For reference here's a Manticore build I use:
Here's a Windforce:
