OP, you are spot on, but people won't agree with you because:
a) they just don't like GAC
b) they've been burned too many and are anti-cg
c) heard people complain that GAC rewards got nerfed and refuse to believe otherwise
d) don't/can't/won't do a summation of many small rewards to see the end total
I've done this a lot, pointing out that a 3-0 week gives you enough GAC currency to buy 35 Kyrotech, which is not insignificant. Seldom do people acknowledge the value in that.
BUT IT USED TO GIVE 50 STUN GUNS!
Yeah, it did. Once, when GA ran half as often.
BUT IT USED TO GIVE 25 SALVAGE FOR FIRST!
Yes, and 35 >>> 25
SEE, THEY NERFED GAC REWARDS!
For d), see how many complaints players have about the Galactic Challenge rewards being nerfed, when in fact you get more than the first iteration. Just in a lot of batches of 2,3, or 4.
So, excellent post, but I think you (we) are shouting at the wind.
