get yourself a pair of Mk. 44s or Peregrine Greaves (RNGeezus blessed me with the latter both this week and last week), put on your MIDA, spec for agility and put on transfusion, then start shoulder charging the piss out of everything. a good shotgun will take care of the ones you miss, too. shoulder charge is some of the most fun i've had in the crucible ever, and the Mk. 44s extend the time you have to use it while sprinting while the Peregrine Greaves make it so that hits from the air (a quick hop before you hit the melee button) do 3x damage -- that's enough to take out bladedancers, radiant skin sunsingers, and AoL defenders. shoulder charge in crucible is so much fun. it should be noted that i'm not one who plays for a massive k/d ratio, if i manage to take out one guy before i go down i'm happy.
