Strike excusive rewards and strike bounties with medals,etc like in ROI but easily available in a book format inside your menu like those AOT style books from late D1. They really fixed a lot of replayability issues with the strike scoring system, crucible weekly bounties,etc. I really expected to see those at the launch of D2. The challenge system is just obscure and silly, and you get nothing for completing them. The random weekly strike/crucible bounties were a great idea that they should have continued. Of course,without random rolls all that stuff would eventually fail anyway. I recently went through the D2 armory on Destiny Tracker,and I had about 95% of the weapons armory within the first month...and as we all know, Uriel's and The Number,etc. All drop with the same roll every time. And,btw..regardless of what the "KellyGreen" says, The Number has exactly the same optimal ttk(1.07) as Uriel's. It's the same gun without high caliber,so in effect it's actually less effective in pvp because the enemy can shoot back more accurately.
