What's wrong with the Ranger class ? What's wrong with the ranger Skills and bows?
For me totally nothing !! I love it to use a bow and in DKS Explosive Arrows is still powerful enough ! Stun Arrows is also very good if you wish to have more time. Use Stun Arrows, then Ranger Suprize and after that shoot arrows

And there're more strategies for the ranger, I'm sure you can find a nice/funny way to play as a ranger. But I never play a PURE class just because I like more variation in my playstyle, combine ranger skills with magic spells and warrior skills, etc ...
For example : use Stun Arrows first, then Rush Attack, use Firewall and make a short end of the enemies life with my Scorpion Sword ( by the way, great sword !!).
The thing is that if you wish to have the highest damage values for your bow you must search for a Magical bow (doing a high magical damage) when you upgrade your Intelligence mostly and choose Balanced bows when you put points into Dex & Int both and search for normal bows (ranged damage) when you only increase your Dex.
