Ornn W/R discussion

So I recently bought Ornn, which i was originally hesitant on buying due the low w/r, and I was pleasantly surprised by how hard I could carry with him. I've only played a few games with him, but so far I've managed to not only be able to win lane but also solo kill many lane bullies such as kled, darius, and illaoi. I personally think that he's in a good spot right now and the only problems with him is that people aren't playing smart, using his kit correctly, or teammates are buying upgrades way too soon. When I played Ornn, I usually went mid lane as soon as I got ult just due to how strong it is, the ability to start the ult Ram to spawn it on top of them instantly in my mind is just too good, and the second cast I think is easily done so I don't understand how people find it difficult. I think Ornn is really good with CC heavy comps but he doesn't need them. He ganks mid lane very well and getting ganks he's amazing at setting them up. In jg I've played fewer games but he seems just as strong. I just want to know what other's thoughts and opinions are on Ornn and why he might seem to be doing so poorly.
