Is buying armor worth it when the enemy has any sort of armor penetration?
Starting with things like
, a core item to most bruisers, and
, a core item to most ADC. And then the are a lot of champion kits that include armor penetration, like Garen, Jarvan, Sion, etc.
As a tank, should I just not build armor, and just stack health like a bruiser? Actually, are there any reasons to pick a tank over a bruiser?
