chaos bolt ?!?!?!?!

ok does anyone remember why chaos bolt was so awesome it was because it was supposes to ignore DMG reduction. it never F***ing worked it has never bypassed a pally buable. the originally reason that my lock was destro before they nerfed the spec was chaos bolt was special DMG that cant be stopped then it was changed in to fire damege that is not supposed to be stooped but they failed so that whole we took it out its a bit OP is a LOAD OF S^&T they never got it working after they made it pure fire dmg.
