Let me start off by saying Long time Halo/Bungie fan way back to the original, and that so far (SR66) that you guys really did an amazing job taking over Halo and making it your own, so thank you.
That being said I have a few suggestions that I personally would like to see brought into the community some way or another in no specific order.
Campaign: Everythings good but one thing, I dont earn any experience.. It almost made me not want to play it, really. Whats the point of doing it on Legendary or with any skulls on If you don't earn anything besides achievements?
Stronger specialization perks: It took 50 levels to get to a specialization and I thought it was going to be beast choosing operator and driving everyone around pew pew etc. but ever since i hit SR60, got the Wheelman tactical package, I dont see a difference almost at all. Kinda dissapointed. Atleast make the emp charge not effect a Wheelman at all.. I cant speak too much about the other because i havent got their yet but I was let down by the Operator.
Stats/Commendations: I like what you did with the Commendation area but at the same time I'd like to view my badges and be able to view other peoples also (Laser Kills, Sticks, Snipes, Headshots, Rocket Kills, etc.).
Balance SP Points: Take them out, theres no need. In any game you have currency to purchase certain items over others, but in Halo 4 you get a SP points every level so on and so forth then u unlock everything by SR50 i beleive. Thats the end of that, got everything. You could just make it to where you unlock them through levels. Unless you have other ideas for spending them?
Spartan Ops: Wow, good job. The cinnematics, the story? all got me hooked, great addition.
Firefight/Survival: I think there should be some type of gametype similar to Firefight like a survival game where you have a certain time limit, difficulty, waves, wave length, skulls, and everything else to test the spartans against hoards of covenant/prometheans.
Halo Waypoint: Not sure if its just me, but im using a Samsung Galaxy S3 phone and halo waypoint doesnt work for me, I can only see my Halo: Reach stats and it says "Sorry, your browser cannot support this page." when I try and get it for my Halo 4 stats.
Thats all i can think of right now, Ill edit in the rest when it comes to me haha. What do you guys think? Agree? Disagree? Suggestions that you want 343 to put in the game or take something out? Let me know what you think. Thanks!
