A random point on a topic done to death.

when champions deal enough hp/true damage to hurt tanks a lot, it means that more than likely it is hurting squishies way too god damned much.

When it is hitting squishies for a fair amount, it means that more than likely tanks aren't getting hit as intended.

And when you try to balance it out by adding extra damage to it that isn't the hp/true, you end up wit vayne three shots.

the real lesson? don't mix hp/true damage ever, it isn't a healthy way to deal with tanks.
