Avid Jarvan player, wasn't even aware of this unit collision bug. But yeah, his ult needs some attention. I feel like more than once I have screwed over my teammates who were trying to escape by ulting the enemy team to clean up but trapped them in. If there was a way to make the ult impassible for enemies and escapable for allies, that would be great. Or at least for allies to be able to escape it if they get caught. Maybe not walk in, otherwise too OP. But thank you for letting me know of these issues. I will not ult a Fizz. X)
