Your first paragraphs got me thinking.. Right now im playing ESO. The questing there works as in wow now. You get a quest and a marker tells you where to go. I dont need to read what the NPC tells me or check journal to find out what to do. The marker is there, run to it. At the same time, those who created ESO encourage us to go out in the world to explore, search, find stuff. Sure, this is how you find the quests, but still.. Its handheld.
Back in classic/bc you had to read the quest text, ask in chat or search on the web on how to complete quests. That shit dont fly anymore. People(the masses?) want fast paced, easy, nobrainer content. Easy storytelling, easy mobs to kill and fast transport. Look at ESO again. You dont have a flying mount but you can teleport your ass around the world. People want to consume content FAST. They want it done QUICKLY and with as little interuption as possible. With flying mounts, this is done fast(er).
