Oh? Not necessarily a problem but very demanding. Frequently arrived BOM at 330T+ landing weight and that leaves no margin for error.
Also often run into problems in continental US were standard operation is 767/330 type at the max but I'm landing at 330T+ with absolutely no comprehension by ATC as to the physics of a heavy aircraft. I do my best to keep my cool but really, some of the controllers just are not in the real world.
