Riot, why do you keep adding more true damage? You're making the tanks unable to survive.
Look at how they're changing Infinity Edge: 20% of your crit damage is converted to true damage. Previously they added in Conqueror, which just adds more true damage, and Duskblade is the assassin's source. The list goes on.
I'm starting to think Riot hates resistances and wants tanks as a whole to be removed.
