Some say bloodrazor is the way to go on jax. They just haven't watched any high elo gameplay of Jax jg or they haven't checked op.gg. anyways that doesn't mean it's bad. That just means it's situational. So when do I build bloodrazor

Cinderhulk if you don’t have a tank or the enemy team is squishy. Bloodrazor if you have a tank or two or the enemy team has an HP stacking tank.
Most low elo players mistake Jax as an initiator and tank and usually pick an AD carry top or mage support. Jax is a skirmisher that only becomes tanky if you use his ult or time his E to lower damage.
He is by no means a tank, but he’s built tanky to survive short skirmishes and build his DPS up.
TL;DR: Cinderhulk if you’re playing without a tank and need to look out for #1, bloodrazor if you have a decent tank and have room to kill folks. You’re not Sion and you shouldn’t play like him.
Jax is all about jumping onto one guy 1 at a time and beating him into the ground before moving on to the next. He’s not there to tank or peel for his team. Play him like Master Yi or Fiora.
I always thought Jax was a diver and not a skirmisher. His q at Max rank doesn't have a 2 second CD like 
(at max fury)
(if he gets a takedown).

Essence Reaver jax would beg to differ.

Tesladin1 votesOkay safe will keep in mind thanks might build that sometimes as well
Linna Excel1 votesI wouldn't build Cinderhulk on him unless I was going for a build with a lot of +HP items. Even then, he's probably only getting about +135 HP total at his 3rd item, if the game lasts that long.
