On day 1 of an event I spend some time online, and every 2 weeks I also spend 2 days doing spire&tournament for under 30m.
other than that I'm once a day for 5m the other ~25 days per month. Rarely, if the event prize really interests me and RL has boring downtime I might log in a second time for 60 seconds to pickup droppings around my city, but that hasn't happened since last winter.
If I spent that little time playing a game, I would quit because it obviously would not have my interest enough to play a couple of hours every day. Heck, with the neighborhood relocations, it takes me 15-20 minutes a day just to make all the visits.
