It can do a lot of damage. Although the testing was done against training dummies, Warrior doesn't require any special movement for combos. With 400 STR and Bravura, I averaged ~170 DPS over 10 minutes.
You should try again using all your cooldowns. Even @ 5 minutes you should be over 210 DPS.
From Sword Oath to Shield Oath Paladin looses, 50 Potency per AA and 20% Damage. AA is ~35-40% of a Paladin DPS in Sword Oath. In Shield Oath it drops to about 20-25% of total DPS. So Paladin is loosing about 15% of it's DPS right off the top.
Warrior gets access to more powerful skills in Defiance which brings it's average Potency per Skill up.
There is your damage difference.
