@4RM3D I suppose, that "Classic" means "classic casual" and "Ranked" means "classic ranked", right? I find those options in poll potentially confusing for strict logic person like me.
Anyway, I played Thronebreaker 3 times (to make 100% achievements) and will not come back to it in near future. However I would like another story-driven singleplayer Gwent like this. So I do not know how to count it as I made full progress with it and there is not anything more to do for me, so I do not play it anymore and even uninstalled it.
I almost never play arena (about once per 2-3 months).
My main mode is Classic Casual, were I play most of my games. I occassionaly play Classic Ranked as well, but much less than Casual.
When there is suitable time for it, I also play Seasonal, but mostly I play it only during first 2 weeks of season, because after that, faction challenge is typically "forcing" me to play specific deck for rest of season (both during challenge week and during reward week), which I dislike and I was several times suggesting limiting effect of faction challenge to just 1 week instead of half of season.
