Someone mentioned that when they tested the challenges for campaigns for each difficulty, the rewards for easy: 5k XP, normal: 10k xp, heroic: 15k xp, and legendary:25k xp. So the total XP rewards for one campaign is 55k xp. On Xbox, with the 6 campaigns, that means we can get a total of 330k xp. My take on the challenge rewards is that with the total of 6 campaigns having 330k xp, that is a wonderful and challenging feature I would take part in for the next season XP grind on Season 2. And it's also a great opportunity for PvE players. I would not ask for anymore improvements on those challenges, because I think of it to be perfect for us. But if improvements have to be made, I would hope it would be a bit better than what is featured today. I wouldn't want it to be over-used. Because when it comes to balance, I would suggest doing challenges for multiplayer depending on what medals you earn in multiplayer. Because the balance for challenges should be that the rewards for both campaigns and multiplayer should equally be worth a benefit for players to be interested in playing in and with motivation of how challenges can get players to not quit matches. For example, if you do Firefight multiplayer, which is PvE, I would think of a easy reward of 5k if the match is complete, without committing suicide in the game to end it. If you commit suicide to make the game end quickly, you don't get XP. For Heroic firefight, I would say for completion, you get 10k. Now for multiplayer, for social games, when the team defeats the opposing team, they get 7k. For the losing team, they get 5k. For infection, when the player survives being infected, they get 6k, and for the zombies who infected everyone, they get 4k. The survivor who has the top lead, I would say 7k. For the zombie who get the top lead, 6.5k For competitive, when the team wins, they get 10k. For the losing team, they get 7k. I would hope for the campaign challenges to remain unchanged for the next season, because I got all the armor for Reach. But as I said before, if you believe there should be an improvement for the challenges, please don't taint it, because I think of the challenges to be a wonderful idea in this current state.
