343, I love your game and its entirety, but one thing bothers me. The amount of XP given through Spops. People who play on Easy and people who play on Legendary get the same the XP, that is unfair. 4 people can go through Sniper Alley 20 times on Easy and earn the same amount if they went through it on Legendary the same amount of times. Its not rewarding those who play on a harder difficulty. So my suggestion is this:
Easy- You earn 1/2 of Xp normally gained
Normal- You earn a normal amount of Xp
Heroic- You earn 1.5x more xp then normal
Legendary- You earn 2.0x more xp then normal.
Anyone like this idea.
