i tanked drusella sucessfully once on my sk last week sometime. go back in last night and just got slaughtered. i would follow almost to the T what is written here, and do a full burn out of taunts, dd'd etc all i can when her shield is down, then boom, knock up and aggro switches to a healer, or someone else. DM, rescue, etc all just do not refresh fast enough to rely on last night. it seemed every 30 sec or so she would knock up and boom aggro gone.
