I think halo 4 should have some sort of ranking system similar to halo 3 but instead of making it easy to do from 1 to 10 in like 3 game winning streak make it harder. I would also like for it to have how many games you need to rank up. Of course dedicated servers would be nice. Power ups in games back would be really nice too. I really think sprint would be nice in halo but nah not evade or the other aa's. I understand people like reach and they want a really fun halo but halo always gave me a competitive feel and reach didn't have that, it was more for the casual CoD player with a few more bullets to kill. I also think they should fix the melee system I mean seriously if the other spartan has the slightest amount of shield it just breaks it. No death :/ makes no sense..
I think they should have a voting system like reach but only with just two games to pick from. That way you cant just veto the whole selection and get a brand new selection of maps and pick the same map and gametype you always do because you don't like variety. Another thing I have been wanting to see in halo is a full color spectrum for your armor something very simple that would be a nice add.I loved the credits personally but it shouldn't be what ranks you up. Experience should be what ranks you up (not skill level but like general and stuff.) I think you should unlock most of your armor through achievements, achieving certain medals, achieving a certain rank, or reaching a certain skill level in multiplayer but you would have to purchase that armor through credits. Some not so cool armor could be unlocked with just credits alone.
Another thing I want is no bloom in halo 4 I mean it is understandable to have less accurate weapons in halo: reach because they were less advanced but keep that specifically for halo: reach. Although I wasn't much of a halo: reach fan I would like to see halo 4 have something similar to the needle rifle come back and of course you got to bring back the beloved battle rifle lol. I have seriously had trouble finding something of a challenge since I quit the halo franchise and when they release halo 4 I truly hope that it will be something challenging. Instead of something to play for a few hours just for a little fun like halo: reach. I wish 343 the best of luck and I have a bunch of fate in them and they will bring it back to the halo we all know and used to love. Yes halo 4 shouldn't be exactly like halo 3 but it should have somewhat of a halo multiplayer feel instead of call of duty. The reason the halo multiplayer was so successful for so long was because it was original and more competitive then any other game. It was similar through the series but a few different things were added to matchmaking each game. Reach completely changed what halo was and made the goals of the game achievable very easily which made me shy away from it.
Well there is what I want out of halo: 4 and I know it is a bunch and I don't expect all of it but I am hoping they will give back the competitive feel i know and love. :]
