So here is my theory on what prison of elders will be Most of you know that someone found data calling the "raid" , "The arena".. Everyone was speculating that it would be a Firefight/Wave based raid with bosses ect. Which would have been awesome. Though many people including myself thought that wouldn't be ver "raid" like. Well what if bungie really wanted to do a firefight type activity but didn't feel comfortable calling it a raid. This leads us to The prison of Elders.. I think it would be extremely awesome if POE was a wave based activity maybe set inside the Prison or maybe in a courtyard out the front. Waves of badass fallen prisoners could come out with a boss every now and then. They could make it raid like with different fallen types we have never seen before (because they have been locked up). Progressing through the waves and bosses could give you rewards based on a raid like system. You could get a few rewards after each boss and then the main reward after the final boss just like the raid. Maybe you could progress through the prison and fight in different sections to change up the play style. They could even make a hard mode that is released later that gives you better rewards if you can pull it off. I think they could make this a decent length to complete (a lot longer than Crotas end) and make it so you can cheese and skip parts, which is what people want anyway. So what does everybody think??
