The Divinity games have always been not very mechanically polished but great for having tons of nonrepetitive contents to explore. Since Divine Divinity it has basically been Larian's game development style. The players should have expected that for D:OS 2 too.
Even if thats true I expect the developer to try and learn from his mistakes and try to be better. If he doesnt that I will not buy his games on release(most large developers). Or ever(eg Ubisoft).
