It sounds like you still have a few chances left if it doesn't say "you are permanently banned" when trying to log in. I wouldn't risk it though.. however if you are already done with the 100 hours of afking you can just log in really quickly and claim the major weekend rewards

These boxes come with a different kind of coupon, not the same Vindicator ones.
You cannot obtain the Regina Outfitter Set, Regina Wings, Zecallion Set, or Crystal Set through the exchange shop.

Individual Item Probabilities:
Packaged Special Regina Set - 0.0367%
Packaged Regina Wings - 0.0587%

Not obtainable through Exchange Shop but it is tradable via the marketplace.
I expect the outfitter set and wings to cost about 1 billion gold each.

I don't mind if they extend this event further, but you have only a day and a half to get a response to this (after the maintenance on 21st begins it would be too late). This might be overlooked on forums so I would suggest making a support ticket.

Based on my past experience with Nexon support, chances are much higher here, than them replying from support.

On a side note, what could we do to get this seen?

Support is pretty quick now, another option would be to tag the GMs in your post
Like this @Sleiyer that might get their attention.

An alternative way to get the high value items via the exchange shop with special currency... And as far as I can tell they all have true RNG in those boxes as well..

Granted not every box followed those rules...like the black Friday sale...

It's not just publishing the rates, it's requiring that all gotchas must at least have a direct purchase option or means of earning them with in game currency, if not both.

Last year's Crimson Commander Packages did have a means of earning them with in-game currency via the 5th Anniversary Monster Bingo. You could claim a Crimson's Commander Package as the grand prize for free after filling out the bingo card (and people could do this on multiple characters) but this year's version of that box, the Black Friday Lucky Boxes had nothing of the sort. Seems like a mistake.
