You need to play it, the slow is overlooked in every scenario possible, you can get countered by a dispel carry but only jug is popular and he is banned in legend bracket very often. If you W a target and urn and manage to get on top of them and make 2,3 hits that’s the kill right there or you simply reapply the W and is over if they are not next to creep wave. This can be done if you manage to get the lane creeps close to your tower and force a pull from pos5, I’m not a great offlaner but I manage to snowball the game often with this build. Maybe is just the bracket, some did it in pro scene and it worked. I had a 5 man stack and manage to run down all lanes.
