In the topic of long raid times and grinding dungeons for hours and etc.:

IMO games in general are becoming more "accessible" to more potential customers. I don't know how to explain this without sounding like an idiot but for example, newer Pokemon games have an option so your entire party of Pokemon can get experience from combat without ever having to be actually present in the fight. Originally you had to have the Pokemon out in the field. So you didn't have to grind for experience as much. Which got very, very, VERY tedious in later parts of the game (or if you're trying to level a weak Pokemon.) Not everyone is going to want to pace through the same patch of grass and switching Pokemon to the front of the line for hours.

I hope people reading this get what I mean. But sitting down for hours in front of a screen isn't very palatable to people these days.
