Jax is still a lot of BS. But tell me more why Aatrox was the problem.

He does a lot of magic damage. You have to build armor and magic resist to fight him.

Old Aatrox got his E nerfed when they changed it from magic damage to physical damage.

Meanwhile Jax's W does bonus magic damage and his ult passively gives him 100/160/220 bonus magic damage.

Lets really look at his. Basically that averages out to him doing 73 bonus damage every hit at the max level. This is ALWAYS on, and in the long run, probably generates a lot more damage than ults that actually do damage when activated.

His counter strike is really BS because it stops all damage from basic attacks. That is a lot of damage to always be stopped. You could have 500 AD and you dont do damage to him, then you get stunned and dealt damaged by the ability and then he just kills you with auto attacks. Awesome. This is basically 3 free seconds where he gets to change the fight while doing damage and CC. Hate it. Always have since day one. Thousands of matches later, I feel the same way.

Very few champions can simultaneously 1) stop incoming damage while moving 2)deal damage and CC from the same ability

And when you fall behind, he stat checks you. Why did old Aatrox get shit on? Jax is way worse when ahead. But oh no, Aatrox was the problem. Meanwhile Jax and others are way worse when ahead, STRONGER when snowballing and MORE effective when behind than Aatrox ever was.
