Asked and answered in my first reply. You are simply focusing on the tiny part that advances your point, while ignoring every else. The things you are complaining about are closely linked to the difficulty in programming a FPS, and getting its VERY timing-sensitive game mechanics to work. Even on-line 3rd person games can tolerate levels of lag (and barely notice i) that would render a FPS unplayable. When I played Titanfall regularly, just 30 ms of lag (ping) was enough to make me lose EVERY 1v1 gunfight. A problem that persisted until I got my ping time down from 80 ms to less than 50. I didn't really become a competitive player until I got it down around 35-40 ms. Whereas with the PC version of Diablo 3, I didn't even NOTICE the lag until it got up around 200 ms.
