[Inaros] is mostly not a team player with his base abilities. With this build, your Roar is competitive with most Rhino builds. The sacrifice is a bit of max health, but you're still at top-tier survivability.

Energy is a slight problem if you plan on keeping up Roar. As long as someone has Zenurik, you can regenerate 150 energy over the duration of Roar. The cost is 116 energy. That doesn't leave much room for using other abilities without picking up energy orbs.
