I'm someone who gets on Destiny and plays almost every day, I've put plenty of time into Destiny, I love playing the strikes and raids, they have a lot of replayability, but PoE is simply not needed. To start, the rewards are absolute crap. A shitty queens weapon, some motes of light, possibly a strange coin, and a shitty weapon from Variks? Come on. And Prison of Elders itself is so boring and repetitive. I still have so much fun with Crota and VOG 7+ months after they came out, but I haven't even played PoE for over 3 weeks because it's boring and the rewards don't even make the grind worth it.
