Even with Greivous wounds, his **MId Game** (note that he does somewhat fall off past level 16 though once the adcs get to full build) is obscene. The amount of damage he takes and deals is absurd. He can run around tanking turrets and 3-4 champions and still not go down for 10 seconds. And in the time that they foucsed mundo the rest of his team either got an objective or killed the rest of them. But if you don't focus mundo he outputs insane levels of damage. I don't think such a drastic buff was needed for Mundo's ult, especially because the thing Mundo does struggle with (Being kited or locked down by cc chains), Still happens, just now he never dies.
