The reason why Aatrox is bad is because of ADC

Adc prevents bruisers from being able to come near them without getting chunked for a large portion of their hp.

Against an APC, their damage is not as consistent as ADC and is much more avoidable than ADC's damage. Also ADC has much more self peel than Apc as well.

In order for bruisers to be viable without being extremely broken and end up 1v5, ADC needs to get nerfed, and surely bruisers will be in a better spot.

Aatrox relies on consistent dps, similar to ADC, Aatrox builds squishy. Unlike ADC, Aatrox has much less range and no mobility to use to escape after going in.

Adcs who also build similar kinds of build will ALWAYS have more impact. For a safe ranged champ with high free damage, they should NOT do more than a Melee carry.

Why does ADC who has more range, a lot of self peel, and even burst(static shiv) do more consistent dps and more burst than Aatrox?

Nerfing ADC will help bruisers make a come back.
