Any Advanced Strats for Improving Drop Rates? ;-p

[Tamu]

Selin has dropped that dagger each time for me when my pally is in the group (tanking), but I've never seen it drop when my warrior is tanking. I still need 2 more daggers for my team (it's dropped a few times while tanking for friends). I've only ever taken my pally into H Slave Pens, and I have 3/3 Pauldrons of Wild Magic, 3/3 Boots of Blasphemy, and 2/3 Quag's Eye.

I've killed Selin 5 times now with my group of 5 shammies. Loot has been (in order):

Plate shoulders, Dagger, Dagger, Plate Shoulders, and yesterday Bracers

... also still need 2 more daggers.
