True damage should not be the go to for tank killing. That is a bad way of looking at it. You already have split magic damage, on-hit health percent damage, and critical hits to deal with tanks. Tanks should be able to itemize against the damage they are soaking, otherwise they can't do their job and prevent their teammates from taking that damage for as long as possible.
