I actually liked participating in EA, there were a lot of nice discussions in this forum. I know, that not all were happy with the results, but the way to the finished game was a good one.
On the other hand: without EA Larian might just be able to release their game as they envisioned it without interference from fans. Just becvause we want something doesn't mean, that it makes the game better.
Or make only a technical EA to test mechanics and builds, don't know, if that is possible.
