As someone who mains WAR and has been leveling BRD, I think this has to do with the ridiculous burst potential of bards compared to tanks in the level range. I've honestly started waiting for the tank to get a massive threat lead before using any direct damage on the pull. If they get some AoE threat going, I'll put up my two dots on everything in the pull first, then pop a cooldown and wail on the first target (which is usually half dead by this point). Never pulled threat early this way!
