I too want to register my displeasure with this change. I play very casually and I got into a nice habit of doing a story mission, then letting the living story marker guide me in the general area to explore next. Usually doing heart quests and events along the way would get me the two levels I needed for the next story mission.
Now I log in and I’m a bit of a loss. I have to level up 5 more times to see my personal story again?
