Does ANet get crash report?
I believe they do. The question is whether they are working to better it or to increase the crash frequency.
The latest implementation of slapping player with repair bill when they disconnect while in combat (while having the good intention to fix the alt-f4 issue) does offer a potential incentive for Anet to implement scheduled crashes for their server. (I only state that it is a potential incentive and I did not state that Anet will act on this incentive)
With each repair bill at 1 silver 64 bronze per player. A scheduled game-wide crash and disconnect willl reap Anet handsome amount of gold each time.
Just a business idea for Anet: if you don’t want to have a bad name for scheduling crashes, you can outsource it out to the hacker who can implement exploits to crash player in combat. You earn your gold while hacker get the bad name. Then you come in later to patch the system and claim credit for your heroine act. Opsss … did I just leaked out somebody’s great business plan?
