When other tank tanking mobs icon show you you aren't tanking (broken shield), is there and posibility show it is tanked by other tank(raid main tank marked) so safe to ignore it? There is some weak auras which show its safely tanked by other tank and make it in blue color so might be blue shild is good for it
