Hi Matty. First off congrats on going DK. 2nd when ZOS fixes the DK class you will be very happy in pvp.

Usually Dunmer DKs are magic base damagers due to all the fire attacks used. If you want DW and 2H you may feel better and get higher results with a red guard or imperial.

Stam go 5 medium minimum for max damage with weapons. Magic go 5 light minimum to yield best results for spell penetration and crit. Regardless have fun bro

DW has one of, if not the, strongest AoE skills in the game

Steel Tornado

A large radius AoE that acts as an execution move (does more damage to lower health targets)

The skill line also received a weapon power buff via use of Hidden Blade skill. It only lasts 8sec and doesn't have a heal like Rally from 2H, but it does a decent amount of damage and also applies a movement speed debuff on the target.

For a Dragonknight, unlike other classes that have their own class skill for damage (I assume you want to magicka), you would combine Burning Embers, Engulfing Flames, followed by Molten Whip/Flame Lash (which ever you prefer, the latter being more PvP friendly), however. Keep in mind that DW, being a weapon skill line, is purely stamina based.

As such, if you go the stamina route, using Flame Whip as primary damage can't really be done, considering you'll be gearing for stam cost reduction in gear, passives, CP, etc. So you'll need to rely on Rapid Strikes from the DW line as well.

All in all, it's a fun skill line that I prefer over 2H, however. 2H is still on top in terms of stamina melee DPS.
