Hey Skari, well done. 2 dreadknights in one shooting phase...whoa! I just wanted to reply to your question about psyker lists.
My last tournament featured superheavy players so I went with a DE/Eldar list that banked on the psychic phase. The results were frankly underwhelming. In 6 games I never got doom and guide at the same time. I much prefer playing just pure dark eldar due to the simplicity- 3+ to hit, 4+ to wound/punch hole in armour.
