I'm SURE someone already pointed this out to u about ur 'wrongness', but im going to just restate it, ur wrong. A tank in full vit will lose aggro to a geared dps, Even if it is 1 enemy, if that dps has a better weapon. For example if it is a warrior they will lose aggro before they finish a storms eye combo, and if they open with a b.b. combo they will still lose aggro because the potency wasn't hi enough without the maim and slash debuff. In low level dungeons I see ur point but doesn't work like that lvl 60+. U get 1 pt of aggro per damage done. + aggro multiplier. If a dps is out doing u by enough do to gear then literally the only way to keep aggro is roll strength. This goes for healers and over healing too. I'm sure u know this.
