Same issue here. Halo 5 multiplayer works perfectly with local LAN fire team. Destiny chokes. So disappointing. I'm actually a new player and bought a second copy specifically to play with my daughter. Spent the evening trying to get this to work. We gave up and just played other WORKING LAN multiplayer games instead. So silly. I thought since this game had been around for a while that basic stuff like this would actually work. It's ridiculous.
