I only buy JEPs now - because I mainly stay on gold and almost never use level IV consumables anymore - always III or less.
Doesn't matter if I ragequit or disconnect from the occasional match, I'm always getting a profit in consumables.
I haven't reached my target of maxxing every rail amp, ammo power and so on, but it will be done.
The few things I run lowest on are:
- strength enhancer III
- cyclonic III
- adrenaline III
- incendiary ammo III
These are all between 100 and 200 - I have been disconnecting and RQing more than usual lately, so stockpiles are starting to go down a bit.
Every other relevant amp (III or IV) is over 200, even shotgun amps.

(I rarely use them).
Level I and II still have a long way to go to max.
