In Thirsty River..

In the Thirsty River mission, which I find is impossible to beat even when I get some amazing groups, is it true that the groups of Forgotten get a DP when you kill them? That sounds like it'd be very hard to prove, but if it WAS true then if you went slow and steadily the mission would be very easy it seems.

I imagine they would get a DP, but true it would be hard to prove. I guess you could try compaing how much of the health bar a constant amount of damage removes or something like that.

Hard? I found that extremely easy - we did it first go with bonus

I think both eneimies and Henchies get DP, yes.
