I notice as far back as 2010 and with pretty much every single Blizzard game there has been a problem with the mouse,either sticking,lagging or not pointing properly.
I have had these very issues for a very long time and it is annoying as heck,to the point i want to quit whatever game i am playing.
Then to add insult to the Blizzard business,i have had ZERO problems with my mouse anywhere else in gaming or on my computer at any time.
So Blizzard owns the distinction of being perhaps the most incompetent operation when comes to having proper mouse stability in their games.
Really pretty sad when we hear so much about Blizzard "polish"well 2010 "minimum says it's been a very long time since they had any distinction of proper polishing their games,especially since the mouse is maybe the most important peripheral we use in gaming.
Never forget 3 mile Island and never trust a government official or company spokesman.
