We at 343 Industries know that many people feel this way. The Promethean Vision is not seeing through wall, it is like have a working visor like in firefight in Halo: Reach. They only show the names of weapons for weapon drops so people know what they are getting when they randomly drop. The guns sound better, you have to play the game to realize the beauty of the sounds. Also, the scoring is the way it is so we can reward, you the player, with more ways to earn points and XP for weapon drops, leveling up, etc. You must also remember this system is just for Infinity Slayer and other select game types. The matchmaking we are using will be stream line so we won't have the problem of lack of players for certain game types. Take slayer for example, we will have Slayer as a matchmaking type but in that will be many game types like, Infinity slayer, normal slayer, classic slayer, etc. I hope this helps change your perspective of Halo 4 some. If you have any questions, please contact me at my email or just PM me through this site.
Finish the fight,
