It's a nice idea, maybe I should try it out, but it feels like items that make you tanky are to be preferred. Dagon w/ multicast for clearing creep camps does seem fun to me though ^^ Also hard to part with my beloved Midas w/ multicast. But perhaps you are right ^^
You have my permission to buy Midas on support Ogre ;) it's actually not terrible. Seriously though, how did support Ogre get nerfed? Seems to me support Ogre should works fine like it did before no?
Small correction: I mentioned the final build has 400 strenght. I'm an idiot, I was looking at his damage. Actually the final build has 280 strenght so that translates into +14% multicast with dumb luck and not 20% Anyways new ogre is so much fun. Any item build that is stronger than this one? Did I forget something? :D
