Half a point removed because the Reinhardt joke in the beginning is patently false. I've never seen a single Reinhardt POTG where he just held his shield and didn't do anything else. Cards are one thing, but in POTG that doesn't happen.
Another half point removed because the animation is very slow at times, such as Reaper and Zenyatta taking two and a half eternities to fall on the precipice once they step through the portal.
Other than that, nice work!
