A fair suggestion for Jhin's (op) ultimate.
It's pretty straight-foward. Jhin's ultimate provides vision on the target(s) which its missiles strike. I personally believe it would make more sense if the missiles were to provide vision on the area which the missiles explode. Thematically it makes more sense that the explosion from the missiles light up an area rather than to stick vision onto a target. This allows champions with high mobility or invisibility to survive more often.
