This was a game that just a week ago I was recommending to all of my friends. Considering the above points, I have lost faith in Larian. Some of these things are far too amateurish to simply be brushed away like the above post tried to do.
I honestly don't know much about Larian but if it's like most indy game developers that have gone the kickstarter route, they probably have a small staff and can only do so much. These guys aren't Blizzard, cut them a little slack; saying you've "lost faith" over one bad patch they're hotfixing the next day seems a little out there.
That said, I actually agree with you that moving to the Steam beta patch system seems like it would make a lot of sense, though I don't know how that would effect co-op play. I know a lot of other indy game developers use that system to help with playtesting new patch changes.
