Sometimes it happens true but I remember it happening with DAI quite abit.
It happens with every single game. It would be unfair to single out either Bioware or CDPR for this. Fixing a problem in a piece of software is nearly always going to introduce a new problem or five of variable severity.
I'm glad I waited to play TW3, because I suspect some of the design decisions that were fixed would have driven me up the wall (weighted crafting materials and no stash, for example). No one can deny that CDPR seems to have been very diligent in addressing these issues in a timely fashion. Whether that means they were in the pipe beforehand versus being built from scratch post release (like I suspect Bioware's BE and stash were), I don't know.
Bioware's fixing things too, though. They've fixed a bunch of the control issues KBM players were having. The Black Emporium addressed a massive shortcoming with the game at release. The biggest problem I can think of that hit their patches was when the shaders and mesh settings got borked and everyone's visuals got screwed up, but they fixed that one quickly enough - not more than a day later.
On the other hand, they still haven't fixed the banter firing issue, as far as I know, which is mind boggling. Something that's so crucial to the charm and character of their game should have been priority one.
