How is dps your issue atm ? You have not gotten to the enrage once, hence it might be how you apply tactics that your group is struggling with.
As for tips, spec KJC + cast incin when you have to move = minimise DPS loss at the cost of a DS charge, since it's a fight where you move a lot, compared to others.
Other than that, cleave with shadowburn more instead of CB maybe ?
http://www.worldoflogs.com/reports/3...?s=8760&e=9088 10 CB crits vs 8 shadowburns, out of the 10 CBs I don't know if any are cleaved or you just cast one to kill the add asap, also, if the 8 SBs were used while cleaving or not, I have no idea ( mind you these numbers are for all the living corr. adds = damage from both you and your fellow lock raider, split that in 2 = 5 CB + 4 SBs assuming all are cleaved for.. how many adds are there in 10m anyway ? 25m raider here). still, I think you can improve by cleaving more with SB and maybe RoF more ? you do not RoF at all, while your colleague might be RoF-ing too much.
There are a total of 13 hits from RoF on the adds and a total of 74 hits on Malk, out of which none are yours. I might not be a destro expert, but RoF usage is still advised to be used on single target under high haste situations only and on multitarget ( when an add reaches melee) I don't see why you don't use it at all, it's not about the damage it does, but the ember generation from hitting 2 targets at once, resulting in (doh) more embers -> more CBs to be cast.
went through the logs a bit more, you used Havoc 5 times while your colleague did it 7 times, if you want to improve, considering cleaving more with this, preferably with SB more than with CB.
that said, gl on him, I have no more ideas.
