to actually get to the point of the OP -

open with Fracture

fracture is a 300 potency attack, MRD or WAR's highest - assuming you don't reapply it early

if you're in the habit of clipping your DoTs, well, stop

as people are saying here though, mrd/war isn't exactly a DPS, although ARR seems to be following the WoW reasoning that became prevalent around the cataclysm era and decided that tanks should do some meaningful damage

so yeah, war and even pld do some respectable DPS - just nowhere near what a competently played DPS class will
