I got to play a sub game like good ol' times, which is going mid, getting a bunch of kills, and then building a midas!
Ogre doesn't normally play mid, mostly because he doesn't have a fast pushing ability before 6, he's melee, and he doesn't have any scaling potential.
If you are playing a core Ogre, blink dagger is pretty good because you can leverage your burst and tankiness by jumping in on opponents and hoping for the best.
From there, I recommend picking up either Aghs, Mek, or some kind of semi carry item like Battlefury. If you're support and playing ogre the correct way, Aghs and Mek are the way to go.
