I think they would lose a lot more funds , I've never bought a camo in BO2 when they introduce it , as for buying weapons ,if the stats are equal to the weapons already supplied then no to that as well, (unless the iron sight is worth it ,no red dot required)
I think individuality comes from earning certain titles/emblems or camo/player card , buying them is only for those who chose to spend $$ so players can maybe comment on.
The map pack is the only purchases I will be willing to my money towards
