I dont think your tanking rotation is gonna with +1 dps. unless they increase aggro gen from BB combo. currently if I open with BB combo and strom eye. I will be really close on losing aggro with a good DPS. i usually like to spam BB combo atleast 2-3 time b4 i start SE combo.

for OT rotation, there no point of being second in agrro list. if anything happen you can just provoke the boss and get aggro instantly. for OT you prolly want to keep your SE and SP debuff up 100% of time so your MT can focus on aggro building. (Pretty sure that SE debuff cannot be stack, if any one can confirm that would be great. I got no idea how SP debuff gonna work tho.)
