Just starting a thread, so hopefully 343i notices it.
The XP cap is way too small atm, compared to the amount of XP gained from doing a mission of Spartan Ops (about 1/15th of the daily cap if you’re lucky), or playing a few games of multiplayer. Either the XP cap needs to be increased, or the amount of XP per game decreased, because there are a lot of people who are very close to starting specialisations…
I was under the impression that the rank system would take a shorter time, but still comparable to say Forerunner rank in Reach. Or am I barking up the wrong tree here?
Second thing is that join in progress system. Personally I think its a great idea, so long as you join when say only a minute of the game has passed, what I’m trying to say is make it fair to the ‘latecomers’. Too many times I’ve joined a game only to be spawn killed immediately, or even a few times about 20s before the game ends…
Also sometimes when I’ve ‘started’ a game, I’ve been stuck on black screen, slowly watching the enemy team get kills on our ‘afk’ spartans, since we’re stuck on black screen and can’t do anything about it. I’ve also noticed on the forums that a few people have had to repeatedly quit the game because of this, and ended up being banned for it.
Also when a new person joins, the entire game goes to black screen, which always happens at inopportune times… Couldn’t 343 implement a system where only the person joining gets black screen, or something?
Other than that, Halo 4 is a really great game, one that 343 should be proud of, and they’ve introduced some great new weapons (not too fond of being binary rifled though 
) and expanded the options available in multiplayer, its just these few things that need to be address soon, to let the game fulfil its potential.
