DOFUS Shop: Decembre, the month of giving.

Exactly!
And like I said before, they have all the game code for the Advent Calendar and Kwismas Island, it would probably just need a little bit of tweaking to make it 2020 date relevant (instead of 2019) then implement it during the *GASP* PLANNED maintenance that coincided with 1st December 2020, so no other time disruption needed like on some years.
Kwismas Island has been around since 2006, the Advent Calendar just as long, yet they haven't bothered.
But nooooo theyre trying to cram yet more unstable, unnecessary twaddle into the game. We have always begged Ankama to fix what is broken first instead of adding "shitake mushrooms"  and "new games" because they're choking themselves royally with the the frack ups.

And for those who think I'm just whining, I've been paying to play this game for well over 11 years, but it's not just a monetary investment for me. I'm in the Extremely High Risk category for the "beer flavored virus" so been stuck indoors since March and can't return to work safely until February at the earliest. My household cant get all hyped up for Christmas because both my kids are High Performance Asperger's and cannot cope, they shut down this time of year, so no decorations, no trips, no christmas shopping, no going to see the lights turned on, nothing. My one saving grace has always been Kwismas Island.
Thanks Ankama for making 2020 even "shitake'r" than it has already.

Oh trust me, after trying to be loyal to the game/company for 11 years + you will see the big deal.

*Content giving - well usually there is 25 days of Advent Calender gifts, yes most are pretty crappy, but it was fun. This year we get 8 days.  Where is the other 17 days of Ankama's so generous content giving. Last I checked, 8 was less than 25.

*Kwismas Island is available ONCE a year for around 30 days at most, not a do the dungeon and you move on like Frigost

*This month, 6 days of the Almanax requires items that are primarily obtained from Kwismas Island, No Kwismas Island = no Almanax. That is Ankama disabling our ability to use a part of a product we have paid for in advance.

*As for new changes, well, they need to fix the old and existing problems and perhaps stabilise the servers better instead of trying to cram new content in. Perhaps try to keep the paying customers loyalty. Which can have the effect of those loyal customers enticing friends and family to play the game.
