ER gives 50%
Jax passive lvl 18 fully stacked gives 88%
That puts him on 2.83 attack speed which is actually 2.5 because you cant go over the cap with those 2 alone.
You also need Rageblade and Lethal tempo AND THEN you also want to buy a fucking Titanic Hydra?!
In what world does that happen lad?
With that build you are going to get popped like a baloon by anything that doesn't need to auto attack you. Not to mention you don't have Conq to shred to anything so anything with a little MR/Armor will tank you enough so his team can mop the floor with you.
If you want to play "suicide mission jax" just play Rengar or Shaco.
