How would YOU change Halo 4's gameplay...

…WITHOUT making it like Call of Duty?

I’ve noticed a lot of people making this comparison over the last few hours and it’s really annoying. People are saying things like Custom Classes and Spartan Ops make the game too much like Call of Duty.

So, if you had to add something to the gameplay what would YOU add? Try not to make it too much like Call of Duty.
