I don't know. When I see gimmick maps like the holiday ones, I generally just ignore them. I'm not offended or slighted that they exist.
I don't especially see a need for a full foundry process for any map that is only going to show up once a year. Oaktown has made some beautiful maps (Eastern Hemi, Route 66, etc) but he obviously phoned in St. Patty's Day. Why wouldn't he? Its a map a small handful will enjoy for about one week a year. There's no need to make that map exceptional.
They aren't real maps, they are simply marketing tools. Every business needs seasonal/event news to talk about. Stay on people's minds. Hell, I'm surprised there aren't more of these. They aren't any good to us super-fans, but to the casual person who pays for premium and plays sporadically, they serve a purpose. They probably get folks back on the site.
Can you say the same thing for some of the maps we spend months/years producing here? If someone posts on the Conquer Club Facebook or Twitter page that the Christmas map is back, I bet that gets a lot more traffic than an announcement about a new map of... Thyseneal? Ancient Korea? Portland?
Everyone posting here appreciates the amount of work and creativity that goes into a good map, but most folks don't. Most folks appreciate novelty and familiarity and they represent a much larger piece of Conquer Club's revenue stream.
This isn't particular to Conquer Club either. Does anyone really find Ke$ha to be a good musician? Anyone actually find Rob Schneider funny or Michael Bay to be a competent director? I bet we all know a dozen extremely talented people that no one will ever hear about. Quality rarely equals popularity.
So... I don't get the fuss. Let them make junky novelty maps when they want. Focus on the stuff you care about and ignore the rest.
Besides, if someone has a St. Patrick or Christmas map idea they want to develop into an amazing, permanent map, who is stopping them? Go post it in the draft room. If its solid, I'm sure it will make it through and replace the temporary crap we have now.
