Actually, I believe that's a good thing : most dailies are already too bloody easy anyway.
But then, truth be told, it's more of a rework that we need. I feel like I'm saying so for pretty much anything and I obviously don't want to sound like a spoiled brat to the guys at Tripwire. Yet honestly, completing map X or killing Y zeds is getting a bit boring after a while.
I feel like having some fancier, trickier objectives would spice things up more. Something like killing 2-3 zeds with a single shot as a support, killing a fleshpound using four different weapons, completing a wave without getting hit and so on.
It would make it feel more rewarding and increase the replay value IMO.
