The reason bruisers are bad
Hi guys so I am a Jax main and I wanted to tell you guys why bruisers are so bad right now. The simple answer is that bruiser itemization is insanely expensive. It’s cost about 10,500 gold for 3 items ( trinity force, titanic hydra, steraks gage). Now compare that to tank core items and you get: 8700 gold for sunfire, randuins and abyssal. No other class core item set even breaks 10,000 gold. Mage is the closest with 9,800 but even then that’s if your going rabbadons early. This needs to be changed bruisers items cost way too much. Here is a link to another post that outlines the cost of core items for each class and subclass for the most part.
and invalidate a tank's entire build with a single item.

9900 Gold
10500 Gold
9650 Gold
