Criminy

lmao got 6 boxes.
3 dyes
1 skill reset
1 prem armor fuse rune
1 appearence alt coupon
lel 30k nx for like 10k worth of stuff

3 dyes that will end up being worthless colors.
1 skill reset that... you should never use anyway.
1 premium armor fusion rune. Legit.
1 appearance alteration coupon. Doesn't matter, so long as you're min height for attack speed this is worthless.

So, what you basically got was a premium armor fusion rune. Which is nice but if you plan well is not even needed as you can do a regular fusion rune first and then enhance and enchant your armor correctly and not have to use a premium armor fusion rune.

Valkyrie's results are possibly the norm for most players. If we look back to the outfitter shop last month, the 'Necromancer' limited time event outfit cost ~32k NX. If that is the value Nexon NA gave to an outfit that players are guaranteed to get for that amount... than the true value of the outfits in the gamble box is even higher. How high? I don't know. But, it was someone's job to do the math and figure out how many boxes players on average would have to open to reach the value they set for these particular outfits.

Valkyrie spent less NX (30k) than it would have cost them to buy the 'Necromancer' outfitter, and the Keag,Tieve, Iset, witch sets are valued much higher than it. I would guess that if you wanted to get just an outfit with no preference, you would probably need to spend 50k-60k for good odds. If you want something specific, quadruple that amount.

Players that get them with 1-2 boxes are exceptions. Nexon capitalizes on these players by broadcasting their good fortune with a 'brrring!' and a pop up to all other players which makes other players more inclined to try their luck.
