Sure man, what was it.
I thought that it came out that what you do in MP affects your SP experience...
I think he's referring to the class. $The class has no relation to SP and MP (I can be a solider in SP and play a Vanguard in MP) but there is a relation between what you do in MP in SP.
Can I play it along with SP or should I wait until I beat the SP some time next May
