Imagine the Dota hero Ursa. Now imagine him in Lol. Now imagine him in lol with all of his kit AND and damn passive. Imagine him not ever getting nerfed... What do you think would happen?
I think the first thing that would happen is people building Atmogs plus a bunch of on-hit stuff and go rape in team fights.
Btw, for those of you who care, I will be releasing a custom champion and a new "Against the Meta" article.
