Look at the difference in damage. Nobody is blowing up, a squishy immobile marksman like Varus isn't immediately dying because of someone felt like flashing on top of him, there's actually room for breathing.
Edit: Look at how there is no free damage, nobody is doing a billion damage because they proc'd electrocute or dark harvest. You either do damage or you don't.
Even Varus who is fed as fuck isn't 3 shotting people with AAs or melting the enemy tank in 2 seconds.
