They're apparently phasing auraxium out to make weapons cost certs, though, which is slightly baffling since I've gotten a whopping 11 certs in the $weeks that I didn't play since the reset, and got only 3 more while playing today
Yes, this is very disappointing unless they increase cert gains a small to moderate bit. It's already difficult to unlock the highest magnification, or reflex scope even, because it's a cert 'tree' rather than pick and choose. If they don't up cert gain a bit and you have to unlock weapons as well, you'll see a whole bunch of default classes and vehicles running around for a long, long time.
EDIT: Also it should be noted that without an increase in certs or decrease in price, the rate of character diversification will more than be halved in a new cert only system since certs currently gain more slowly compared to today's auraxium system, so if they make the auraxium system into a cert based one and don't change either cost or cert increase rate it means fewer different guns AND attachments on both vehicles and infantry weapons.
I suppose it depends on how long the devs think unlocking things should take. Other than the cheapest certs like flashlight, level 1 flak armor (1 cert), first C4 (4 certs), and class necessary things like medic healing (1 cert) I think I've unlocked the first level of zoom for the Flash 20mil, and the first scope for the infil's sniper rifle. I'll have to check when PS2 servers return how many certs I had overall (unless they do a char wipe), but I think it was around 50 or 60ish.
Also today some Vanu were exploiting the Phalanx turret's graphic bug; they'd turn the turret around and wait for an infiltrator to come try to hack it to pull them out. The bug was it looked like it was facing outwards. I yelled out to warn the NC in the area and a vanu actually had the testicles to send me a /tell whining that I was crying about dieing (to their exploits) when I was warning other NC away from doing the same. They left shortly after a bit of mocking in /yell and being warned another bug report was sent in with their name in it. Sometimes bragging about getting 17 kills through exploiting can make you change your ways apparently.
