Loving Ornn but I have one issue with his kit
With a 2nd cast of his ult he charges to redirect his ult, but he already has a charge. I think it would be more balanced if you got rid of his 2nd cast to charge and make his E charge do the redirect instead.
Its like Xayah with her root with E. If her E is on cooldown but she ults then she can't root. Its making sure to keep one key ability to bring out more power in another.
If Ornn has used his E charge then he cannot redirect his ult. This can make the difference in a bland Ornn player and a Master Ornn player.
Just my opinion though.
