Thanks for the feedback and sharing. I know some guides have multiple builds, but this is honestly the only build I run, although I've tried others extensively. I use only this build (Robo) cause I felt I had the knowledge to discuss and share it. When I played Grav Bomb builds I felt very replaceable, and I never played a game where I felt in control of turning it around despite bad teammates. The Grav builds are like you said "dmg/team", although I feel a bit disingenuous actually thinking it's a "damage" build. The core would be the ult, which relies on very good team work, and honestly still disappoints me even when playing with a team of friends, this could just be personal preference. This build (Robo) gives me what I like, control. When playing this build (Robo), you are a presence, you can't be ignored, your not just a Grav ult. You do good sustained damage in area's and medium to long team fights, you clean camps fast and easy, you can solo bosses, you can rip through lanes. So anyways =), I'll leave the Grav Bomb builds to someone more qualified to write them. Thanks again for the feedback and vote.

Thanks for the feedback =)

True, but you still get the reduction for soloing bosses, plus the bonus dmg for minions around you.
