Returning player new to Thieves
Hello, welcome to the shadows.
Here are some tips for D/D newbies:

D/D is viable, but as you have stated, D/P has more utilities, and you can use all of your weaponskills. D/D #3 skill is almost useless in a power/crit-build, and you have good mobility from the gecko so you don’t really need skill #4 either (and most of the times it won’t hit). So there you go, you now have 3 skills you have an use for.
That being said, I use D/D the most, since I like the playstyle. I do however wish it had some more utility as D/P offers.
Watch some good youtubers to learn. And play with builds your self, learn the ins and outs of your traits and skills. That’s the best way to learn.
