The fastest way to level?

[B'Gawk!]

I would really like to be getting into the S rank missions ( and preferably level 100 ) very soon, what is the fastest way to do this after completing the story line missions? Are there any particular missions that give exceptional experience points?

just hunt weps on A ranks, and you will level fast. Doing missions where there is stuff you want is the easiest, most enjoyable and oh, easiest lol. this is just my opinion though. i dont know the details on which mission gives more exp/mp....i just hunted and got my levels fairly fast..im level 101 with only....50 hours maybe...and i have many 50% armors, and great weps!
