*sigh* You do realize that if Halo continued down the road that it was on, it would become obsolete so fast your head would spin. Custom classes are strange, true, but that doesn't mean that I don't enjoy them.
Perks add more depth to the game. Same thing goes for AA's.
There is a ranking system, for God's sake. It's not visible now. It will be in less than a month.
Everyone used sprint all the time anyway, so why not just give it to anyone? Also, what couldn't a super soldier sprint in the first place...
Also, it's not best to say that you've been playing longer than "you reach noobs". I've been playing since CE too, but that doesn't make my opinion more or less valuable.
