>>5561965Because the massive damage from her ult is now physical and doesn't scale with magic penetration anymore. It still has a massive AP ratio compared to other AP champs, but you're a sitting duck in the League of Assassins. This is also conveniently why MF is currently out of meta as an ADC.
>>5565393As of 3.12, Triforce is now OP and obligatory on almost every bruiser who wants to build damage into tankiness. Triforce Bork into tank items (Sunfire, Visage, Randuin are good choices) will make your split-push and single-person duelling terrifying, as well as giving you the sticking power to dive pretty much anyone you want during a teamfight. Hydra rush is fine because it provides a huge power and sustain spike, but Jax gets so much free damage from his W, his champ passive, and ult passive that rushing Hydra is a bit overkill into the offense department most of the time. (of course, all item builds are situational and dependent on play style and personal preference, so do whatever.)
