I feel it from the other side. I have gambling aversion and can't touch drafts for this reason, even though it's my favorite format. It feels like I have to win to recoup my "investment" and I just hate that, even if the actual cost is less than a buck. It's weird because I played on the PT back in the days, so it's not like I can't stand competition. There is something in the F2P model which is toxic for me.

The other huge factor is how frustrated I get with my opponents for playing decks I don't want to play against, e.g. when I face the 5th RDW in a row in unranked with my turbo durdle jank. Part of it is the F2P model again which pushes people to grind with whatever deck grinds best, but it's also the lack of social features. In your local game shop you get to chose to play with people in the same mindset, and talk with them and pick an appropriate deck for the mood of the moment.
