Just thought I'd share a small trick I've been using to increase my opening burst, and it involves the T12 warrior dps gear:
(2) Set: Your Battle Shout and Commanding Shout abilities increase all physical damage you deal by 10% for 12 sec.
Equipping 2 piece pre-pull, shouting and then putting your proper gear on (which does not remove the damage increase buff) gives you roughly 10 seconds of increased damage, which I thought seemed pretty decent. This is only a marginal gain overall of course and if you muck it up you'll screw your dps over completely but for those of us like me who like to min/max it is an increase in dps.
