Why not?

I do have issues with the chapter set up. It’s not the season pass that is the issue, it’s drastic changes being made to the game and the map that are removed with the next chapter.

Now my question is, once they get a couple of years of battle pass and season events done, and they go in to auto repeat, are you still going to be playing and buy the pass?

The real issue with the battle pass and season events is they are designed for transient players. Short termers that will only be playing a season or two and move on. That does not describe your common Conan exiles player. The way it works is it seems you play it, love it and put a few thousand hours in, or play a day to a week, hate it and quit.
