I just changed my subscription from 6 months to 1 month. If the following major issues are not resolved in one month then I will be unsubscribing.
1. Ability Delay - You should know better than to have released with an issue this big out there
2. High Res Textures - They were in the game outside of cutscenes in beta. Re-enable them and allow people to decide for themselves if the performance hit is worth it. You decided for me that my machine can't handle it is unacceptable.
3. User Interface - The UI is terrible. Not even implementing basic UI customization like being able to move windows is unacceptable.
4. Error 9000 disconnects - Even if you can't actually fix the disconnecting problems, you can implement things that mitigate the pain it causes like holding peoples spots in Warzones and not killing players that DC in flashpoints.
I'd say those four things are the biggest issues you have at the moment. Get your crap together Bioware. You are wrecking your reputation by not having these things fixed at launch. I will not accept that you are aware of the issue and are working on it without a solid ETR for the problems.
