They already said they're going to enhance QD with native debuffs.
I don't think DP needs any kind of revamp, it's already a very good weapon, a weapon that allows you a different play style. On Armageddon you're forced to use Tact/Miser for the WF spam, while with DP you can focus on more dps(even with more direct damage increase rolls).
Situational? Yes. But everything in this game is.
You want to get your DP? Go ahead, it's very good and neat as hell with that look of portable cannon(a very important factor if you ask me).
