Well 70 seems high but from the videos they just added an extra 0 to the xp to make it look better or something...Like instead of 5xp for domination they were getting 50xp. They said they changed the xp system so it will probably level up close to the speed you did in cod4 I'm guessing.
Plus there are those challenges in the gameplay videos that you can repeat like if you stop an enemy short of a kill streak you get 50xp each time you do that or if you get the first kill in the match you get 100xp etc. There were a lot of them if you watch the videos that ranged from 50xp to 550xp so if you're good at doing those you can level up faster.
I don't know what the pavelow really does yet it just seems like a better chopper.
