I think they are pairing the faction weeks depending on the season name. Mahakam was ST, wild hunt is MO...It's really bad luck that the broken factions correspond to their season name.
Bad luck, really? That's what you call it? I remind you, this game is developed by CDPR, operated by CDPR and marketed by CDPR (and it's child company GOG). You can call this anything but bad luck. Incompetence. Inability to listen and/or react. Making bad choices. And so on.
I don't even ask why they won't make balance changes during a season (like ALL other companies do, and nobody ever complained about that). But I ask why they constantly promote the faction (or factions) that's already everywhere?
I am not only talking about monsters and ST, they did the same with faction battles, choosing two of the most popular factions. Do you remember when everyone was playing coinflip abuse Brouver, and CDPR started faction battles event including ST? I actually easily got rank 21 that season by playing anti-Brouver Skellige deck, but it still wasn't fun to see ST as an opponent 90% of the time.
Ok, enough ranting. I had a little hope after their last stream, but now I see they never learn.
