Why is it okay for Jax to be able to deal more dmg than anyone else while being tanky?

His ult passive damage is straight up ridiculous...
Passive: Jax deals bonus magic damage on every third basic attack within 2.5 seconds of each other.
Magic Damage: 100 / 160 / 220
Usually you would expect someone like
who relies on AA to be quite useless in teamfights, well Jax and his ADC had the best peel in the world...

My whole team was afraid to engage and we just lost that game. I was playing
in top and I was actually winning against him until he was picking off kills all around the map. I tried to splitpush at one point and got camped by
. But I did try to help and save my teamates as much as I can but they just get 3 hit killed or just one shot by
who were both full ap.
