Damage outscales defense to the point of khazix being able to duel tank amumu all game long.
I went tank amumu, he went khazix full ad all game long he out sustained, out damaged, and out lived me. The game ended with them taking baron and elder 10 seconds flat in the time it took me to walk to baron from mid they took it and ryze ulted to mid in the time it took me to get to mid to elder they took and they just solo ended the game, prior they took baron and took all of mid and the nexus towers since we couldnt stop the endless push mid. This is how the average game feels for people who play tanks as tanks instead of AP ONE SHOT GERNADE AMUMU BUILD!!!! You fight someone with high damage they kill you early, they get a lead, they get armor shred by the time you actually finish some items, and bam they death ball mid and the game is over. No stopping, Objective after Objective, No Backing, No fighting, Just waiting for them to push mid in 30 seconds and end the game flat out.
