You are not wrong, I only play each season until I complete my entire season journey, then I quit the season until new season kicks in. I had been playing like that since Season 4.
I am not a terribly serious player either, I actively avoid pushing high grifts unless it is absolutely necessary. I only did so last season as a test to see if I can make it to the leaderboards, but the leaderboards in Asia is much more vicious than US server.
I haven't checked the final leaderboards positions, but on Asia, the Grift level I got when I pushed to 80, was in the bottom 200. In US, I would have been a LOT closer to top 200, but US leader has higher Grift level than Asia.
I gave up after about 2 weeks, I don't have the will power to keep pushing for the entire season, and I was time constrained (I have less playingtime in 5 weekdays than pushers have in 1 weekday), so I settled with timed leaderboards (EG conquest leaderboards).
I am not doing any of it this season, just going to come in in the middle of the season, get journey done and get out until next season.
Yeah you see...I have no idea what you are talking abut there.
