Rumble is an underplayed, and fully overlooked champion. For those of you who play him, know how good he can be. I fooled around with some bot matches to see how well he could sustain as not just a tank, but a heavy damage dealer as well. Incorporating a Hextech Gunblade in the build was my goal, along with a ton of ability power. This build may sound ridiculous but i assure you, you will not be dissapointed. Rumble is a Ability power based DPS Tank in my book, and a powerful one at that. IM NOT SAYING YOU WILL CARRY YOUR TEAM TO VICTORY, what i am saying though, as that you have the potential to be a very big threat. Enjoy! This is my first build that i have submitted and hopefully wont be the last.
