I mean, don't get me wrong... I loved WildStar, but I'm under no illusions that the difficulty curve was the only mistake the game made. But it was definitely a mistake, and one that I definitely don't think helped player retention. Since I personally knew like... 8 people who hit that level range and noped out, saying they played games to relax and didn't find that sudden cliff relaxing. Or enjoyable.
When 0.05% of your playerbase sees raid content, thats a red flag something is seriously wrong.
