What I want in the future of OMD

I loved the latest DLC with yetis. Not just because of yetis and beautiful ice cavern theme. The maps had very intelligent design and were very challenging even on WM difficulty and forced me to think a lot.  First time you play The Hive the first thing in your mind: "this is going to be fun, I'll be just massing push traps and... oh forget it."
In all three maps I also liked the lack of possibilities to conveniently combine swinging maces with tar traps which has made many maps boring.
 
The maps of other two DLCs were somehow too obvious although the new enemies and traps/weps/trinkets were cool.
 
I have also enjoyed some of the weekly challenges a lot. While in some challenges you were just given a bunch of random stuff without any clever meaning behind them (at least not any that I could figure out) I really enjoyed those where you have to find a way to combine what you're given for effective results. 
 
I actually wish that OMD3 would be mostly based on these kind of challenges where you're forced to use a predetermined set of items.
