I agree, the problem I have is more about his blade being really strong and his base kit being weak, overall he is balanced, but it would be nice if we could powershift some of the power of his ult into his mid fight.
I’d say nerf nanoblade and his ult cost, and buff his base damage and some other small things
I’ve made a post not to long ago about changes to genji
Here it is in case you want to read.
