I was thinking about the price of mod calibrators on the Auction House, and the people who farm the Blast Network for Krogmo coins, so I decided to do some back-of-the-envelope estimates. If we make the following assumptions:
6 min per BN run
1.5+B krogs earned per run
100cr cost per run (~50% win ratio, actually less)
and
C as the number of crowns per CE
S as the sale price of a mod calibrator
N as the number of sales made
The cost of a single mod calibrator (crowns):
50/(B+1.5) x 100 -> 5000/(B+1.5)
Break-even equation:
N x [0.9xS - 5000/(B+1.5)] = B x 300 x C
Time needed to earn N mod calibrators with B boosters:
50/(B+1.5) x 6 x N
Thus, a table below sums up the number of mod calibrators you need to sell to pay off B boosters and the time T it takes to earn them, given C=53, and the sale prices indicated (here, 10, 15 and 20kcr).
...S=10k.....S=15k.....S=20k.
B..N...T.....N...T.....N...T.
1..3..360....2..240....1..120
2..5..429....3..257....2..171
3..7..467....4..267....3..200
4..8..436....6..327....4..218
5..10.462....7..323....5..230
6..12.480....8..320....6..240
Based on this cursory examination, right now with the price of mod calibrators hovering around 15k, it takes more than 5 hours of constant play to break even (buying 6 boosters), and you have to make 12 sales. Even if mod calibrators were selling at a cool 20k, it would take you 4 hours to earn the 6 mod calibrators you need. In short, investing in boosters for selling mod calibrators for profit requires one hell of a time investment. You would be far better off spending that time adventuring (i.e. an arena loop), and taking the earnings to the AH to buy a mod calibrator than farming your own. (Although, if you did sink that much time in to break even, the profits would rack up fairly quickly.)
Based on current mod calibrator prices and their trend, people are seriously undervaluing their time. I can understand buying boosters to get mod calibrators for personal use faster, but that's paying currency for time. If you're in it for profit though, the numbers would seem to suggest you're doing it wrong. Along similar lines, the only other valid reason for getting boosters is to earn krogs for Sullivan's bomberhead masks, which can't be traded.
Of course, numbers are only as good as the assumptions they are based off of. So maybe I'm just a fool for not jumping aboard the bandwagon... any thoughts?
Looping arenas is an exploit and boring. Blast Network is fun. The Mod Calibrators are simply a bonus.
