Possible Changes to Mundo's W, Burning Agony.

If Riot is thinking of changing Mundo's skill, Burning Agony. I want to make a discussion where fans could offer their ideas on what could better fit Mundo's theme.

I believe Riot could give him an active skill where over the next few seconds, every time Mundo received damage, it would increase his passive until the duration ended maybe even giving a small burst of movement speed after the effect enters cool down. I find Movement speed is very important to help Mundo go where he pleases. But so does the passive tenacity on Burning Agony. They could keep his passive tenacity on the new skill or apply it to his ultimate scaling. I'm not sure on exact numbers or scaling but that should be left for Riot to decide anyway.

But this was just one idea of a skill to replace Burning Agony. Post your own ideas/suggestions and perhaps one will be adopted by Riot to help Mundo become the best Mundo he can Mundo.
