Sorry, but you've contradicted yourself enough to the point where I won't "defend" an explanation of mechanics. Things work how they work.
Elaborate. If formatting was the problem then it's taken care of.
The game is having "normal" drop off tendencies due to mechanics that are by design.
What I'm complaining about is one of those designs. I've heard a lot of "that's bullshit" in mumble from friends experiencing the same thing.
However it would seem that there's even more due to the changes that have been coming as of late that are based off reactions to quite a few factors like bots, inflation, barrier to entry to inferno acts, etc. I didn't play any other diablo, so I don't know how things were handled in their early days.
The changes of late actually magnify the animation problem. Higher repair costs and frequent insta-regen elites make deaths from this all the more frustrating.
