Online coop truly makes games more fun, imo. If online functionality is used for more technical power, it would also be more fun for me, because I'm interested in technology per se - so I'd love to see, what will be possible with this "still new" way.
Of course, I have to wait for friends, when I want to play online - it's the same, as when we're playing a board game at home. This fact makes a game sometimes more worthy, because the time we spend with it is more entertaining, than playing it all alone - this sounds paradoxical, but the lesser time this sort of gaming is available, makes it even more interesting, when it really starts.
Technical problems, as disconnects or network failures, are not meant with this, of course.
But in these "8 hour games" times it's sometimes a good thing to wait for friends and have a good gaming session, which will be more remembered later on, than rushing through, like we all actually do sometimes.
