Pretty fun overall, with friends. Playing with randoms is pretty ass in my experience though, because inevitably 2 people wind up hoarding way more items than the other 2 ever could, so you and the other unlucky schmuck just get carried for the rest of the run until you can somehow catch up. It's happened in every single random match I've ever played and is a huge detriment to the overall experience. It makes the "Co-Op" feel less like "Co-Op" and more like a free-for-all. The only time it's felt like a proper Co-Op is when playing with friends, calling out what items you've found, and decide if it'd be an item better for your desired build or for one of your friends.
