Fastest way to get to DZ75+???

[onebadmofo1989]

I'm currently sitting at dz rank53 with 300k+ dz credits, and I'm just wondering what the fastest way to rank up is. Wanting to get my hands on the Vector blueprint from dz3 safe room vendor and many more when they come round

Here's the secret.....GRIND

The fastest way to level up is also the fastest way to level down ... Going Rogue and more importantly surviving the Rogue timer will net you the most XP in the DZ. Had a run last night where a friend of mine went from DZ lvl 49 to 54 in no more then about an hour or so by going on multiple manhunts and surviving. Kind of lucked out that the server wasn't to busy and those that were in it didn't have the proper gear to take us down. 

Only down side is if you do die then all that XP you gained goes away just as fast. Otherwise as @HHHope said the only other way is to grind away.
