Corypheus bug (again)

I know that this bug was reported a long time ago but I wanted to post my own topic to express my feelings. I always judged the people who said that they are done with Bioware and their games for whatever the reason was. But now I am begining to understand. I am not saying that I am done with Bioware.It is just that I am a bit disappointed. You guys at Bioware make  the best games from my point of the view, but there is one thing that bothers me. No it is not the paid DLC... i get that. Everyone has to make money but why dont you release more patches? I mean when The Legacy DLC came I downloaded it and had a lot fun with it. Until I came to Corypheus. He always remained in the center and didnt attack in the last round (and yes I destroyed all shadows). I played the Legacy 5 times and it was the same every time. Then I got new computer (unistaled DAII and Legacy). Today after two months I started to play Legacy again. Then I came to Corypheus and he came down in the last round from the centre. WOW. But then again his health remained on the minimum and he didnt die no matter what I did or how many times I played the Legacy again. So there you have it. I am sorry Bioware to bring this up but  it seems you always leave your masterpieces undone. I mean come on I read that Witcher 2 will get patch 2.1 in the upcoming week. Keep the paid DLC but please fix the bugs if you can. If you cant explain at least why (I am not going to comment  the DAO). But to end this "letter" on the fun note. Is this the sign I should get a normal social life and quit playing video games? Cause this bug pushed me close to it. But you are not the only want. For example Techland and their Dead Island...its too sad.
