Credit Heist!?

I only need 432 million credits to level up all of my unlocked characters to level 85. Than add another 216 million to upgrade all the mods needed for those characters bringing me to a total of roughly 650 million credits. With my luck I usually get around 5 million in credit heist so I only need about 130 of them. If they are at 10 days apart that's about 36 per year which will take about 4 years.
