Agreed, been my complaint for a while too. I do think they have obstacle course challenges (especially netting related) but it's lackluster overall compared to years past.
Evolution of the game has to happen and I appreciate that there's more balance towards brains or strategy compared to just raw brawns but let's mix it up a bit more.
The complaints years ago were valid IMO that physically weaker players had a harder time sticking around to merge because they weren't seen as an asset to challenges and then at the end you may not have players who could play the game well and instead just strength driven but it's leaned too far towards the other way for longer than it probably should have.
