no one? i already spent 20k on a respec. there must be a way for me to kill more then 1 or 2 enemies.

Well, the choices do vary depending on situation. I use a Heavy Armour build with spike armour and ransack (because absurd levels of armour are useful for dragging out battles), and combine high max health and high magic regen in order to make Dragon Blood as effective as possible. Obviously this is a tank-type build, but it does pretty much guarantee eventual victory against any foe (assuming you don't make mistakes) that doesn't either massively out-stat you or else have a fair few buddies along to tip the fight's favour. If you're mainly fighting singular enemies, Searing Flame is DK's most cost-effective attack, and against large groups of other foes, use Talons and positioning to effectively turn it into a mostly -single player fight (Petrify can work better, but you need to make sure you're not using DoTs or AoEs. That'll be something you need to decide before you start building). Anyway, for the last skill, I'd recommend something that uses stamina and preferably provides something tactically important like crowd control.
For the ult, I'd suggest Mighty Standard or magma armour. Remember how I mentioned that caveat about being beaten by numbers or higher stats? These two choices cancel them out (though obviously each is best suited for a different caveat).

At level 37, I have 5/22/10, though I'm now mainly pouring my stats into Health. With the way Dragon blood functions, it heals you based partly on your total health, so it can be efficient to just pump that.
