Granted, this is my own opinion, so take it as you will.
We all know the general reaction to people who state that they will be buying cash.
"You're part of the problem."
"You're an idiot."
While these things are probably true, and while it really does little more than allow skill-less players to get whatever they want, they can hold another purpose. A grand purpose. One that makes everything okay.
We all know that losing money in Deathmatch/Missions is a bug. I can't tell you how much I lost before finding this out. Would you say it is acceptable (i.e. not a f*cking retarded move) to buy a 100k cash card to make up for the difference the bug has cost me?
