After reading through alot of the comments I've noticed a common theme among you peoples...mainly being afraid that this will be a once a week type of deal. I can really see Bungie doing it this way as it would fit the model they've already shown us with the Weekly Heroic and Nightfall. My hope is that they don't do it this way and offer the Arena mode as something like the strikes, where you can play it whenever and however many times you want. One thing that would spell death to this mode though is having to take 2-3 hours in it to begin to see some sort of benefit. Players on general don't have that much time to invest at one sitting and if it means your progress is wiped every time you log out, oh well, players will just do something else. I'm really glad Bungie decided on 3 person fireteams as it was hard as hell to put together 6. It even takes sometimes up to 5 minutes to get enough for the Crucible these days, so I think 3 person teams for the raids moving forward would be an excellent idea as well. We can only hope Bungie realizes this and makes the right call. Thoughts??? Cheers
