You aren't alone. My entire guild is looking at quitting come 5.0. Hell, we have people cancelling their sub now. Granted, we are a small guild (~20 people), but that's not peanuts if a sub is about $164 per person per year.
Hope you are reading this Bioware, you are finally pissing off the people who stuck around and actually paid you guys for a piss-poor performance the past 5 years.
Yes, I am salty, and have every right to be. This game has been mismanaged to all hell.
