So I've been falling behind a lot of the people I know who play the game and I feel like I'm missing something, perhaps?
Doing DE's and story quests have been my top priorities.
Some DE's don't give great experience, others do. More than a few of them I've done more than once. I do the story quest once I get to the right level unless there is a DE going on.
I do hearts, explore, grab 'points of interest', and gather crafting materials whenver there isn't a DE going on. I also do jumping puzzles any time I come across them.
I know rushing to 80 isn't the aim of the game, but I'm starting to get close to 10 levels behind some of the people I know who have /played less than me. Something has to be missing from the equation, just not sure what it is. If I don't make it a point to travel to another race's zone of the same level I start to run into issues where I'll be two levels under and have completed everything in the area before.
