If anyone thinks they need it, I can do a write up on how I beat the Champions quickly. Not that I am a super star or anything special but I helped my step mom (who boxes these dailies too :D) go from winning 1 out of 3 or 4 duels - with an alt DPSing the NPC - to finishing the Valiant version in under 5 minutes for both of her toons with no help, she is even faster now. It took about 5 minutes of in game Demo time and talking over vent.
Strafe circles around the npc while spamming 1 and 2. When it runs away, hit charge and repeat. Refresh shield after each kill so the timer doesn't fall. I do this on all 5 alts to solo-kill champions/valiants and generally kill all 4 champions without heals and ending up at ~75% health. Takes 30-40 seconds to kill each one, as shield generally has 20-something seconds left when it dies.

For the Battle Before the Citadel, I just spam 1-2 and never charge. It kills even the Commanders in a few hits and the charge always causes at least one follower to turn the wrong way and stop following.
