i actually just made a post about this, if you want to do some damage (still Sub-par), you cant try going:
- Forgefire/abyssel Mask
- Manamune
- Abyssel Mask/ForgeFire
- Boots of choice
- Triforce
- GA/Thormail/witsend
This give you a surprising amount of damage (for ornn) but it is really exspensive so theres that. The other thing ive noticed is that if the other team has a Garen, Darius, or Cho, you shouldnt play Ornn at all because they all out damage him through the entire game, they all get tankier way fast than Ornn, and they remain tankier than Ornn (even in his regular builds) until extremely late game when they are full build and Ornn catches up. idk Ornn seems super underwhelming, but with a bunch of potential if they changed a few stats and maybe made him scale in only one way instead of AD on q, Health % on w, Armor/MR on e, and 20% ap scaling on his Ult. Hes just a bit to all over the place in my opinion
