Haven't bought the full game yet, but I really did enjoy the beta.

I only have a few complaints, and the one that really bothers me is the social feature imo. They need to add an easier way to chat with random players and to join a fireteam, whether you're in a planet or the tower. The only way to talk to people is to party up with them. Not to mention you need to go through the whole console's interface process (PS4) just to send the request. It's troublesome if you just want to do missions with randoms or just to socialize in general.

As for the bosses, I do feel that they have a lot unnecessary amount of health and very limited move-sets.

Overall I think it's a really fun and enjoyable experience, especially with friends. Playing solo feels really dull for me, so I really hope they'll implement some chat features.
