have they said something about changing origin character attributes or classes?
also is there news regarding party after act 1, can you keep everyone or only 3 + you obviously will stay
Ooh, it didn't look as though we could change the starting classes of the origin characters other than The Dark Urge (for whom we can select class, race, appearance, etc), but I'm afraid I didn't actively check what we could change. Fail! I wouldn't rule changing stats either out or in, based on my memory.
And it has been confirmed that there will be no automatic party lock at the end of act 1 - it was the plan but has been abandoned. Party members might still leave at certain points if they really don't get on with you or agree with what you do, but that will be tailored to each individual companion and the story rather than a D:OS2 like mass dumping of companions at a particular point in the story.
