None of these are Biowares problem, except the ability delay but that will be patched and is not gamebreaking as it isnt a constant.
Framerate is you, get a better machine, I dont have any FPS issues.
Customer service is awful because you are attemting the impossible, you cannot get a refund for opened software anywhere on the planet.
Patcher is a patcher, it does what it does, how can this even be a complaint.
Hero engine is fail? How? list something, anything, 10 hours will not give you an experienced enough feel for that at all.
You havent listed anything but one, and that one will be fixed.
