If you haven't seen it already there is a new champion spotlight for the "remastered" jax. In all honesty they haven't really remastered him, just removed dodge from his skills and mixed things around.
Now to be fair I don't play Jax and really don't have any interest. But from what I gather his passive has been severely butchered. His E skill is now Counter-Strike. This should be an interesting skill to get balanced right. If the duration/cooldown is too long there could be sever drawbacks in using the too early/late. We will have to see how that plays out. And now his ultimate appears to be a sort of splice of his passive and the old ultimate.
The Youtube community seems to up in arms about the new changes. That this has "ruined" Jax. We will have to see really, there are several ways it could pan out.
All I know is Riot really needs to figure out their champion balancing before releasing/changing champions. I mean even Viktor who was recently released has been majorly buffed due to his poor performance. He just doesn't compete with other mage casters.
Come on Riot! You have the ability to balance and fix champions accordingly, so do it baby!
