That's pretty lame imo.
All the unlocks and prestige etc keep the game interesting and give you a sense of satisfaction and accomplishment when unlocking or prestiging.
What's the point of it when you hack it? /
In COD4 and WAW I went thru all the prestiges.
My first copy of MW2, I went up till 5th prestige when it got banned for using console. On my new copy I decided not to prestige, I am now unlocking all attachments, camo's etc instead, which is a lot harder than to get prestige.
