The seasonal activities are tied to owning the season pass for that season. So yes, if you wish to run Wrathborn Hunts, Battlegrounds, or Overrides you will need to own passes for seasons 12, 13 & 14.

Well, that's a big rip, I know it says that I can buy the deluxe upgrade for access to past and future content, but I don't wanna pay $30 just to do that, and I don't know if that'd even work anyhow. I find this to be weird especially when a season ends and you can't do anything to access past season content (Here I'm only talking one season back).

If you hadn’t bought season of the splicer during season of the splicer, you wouldn’t have been able to play splicer stuff then either. No matter what season it is, you need to have purchased the season that the activity is associated with.
