I agree with that. I decided to skip Athiss and stop doing space missions since I was overleveling the content too fast. Once I get to a planet that isn't as interesting I'll probably skip all but the class quests!
Seriously OP, go even to 40 - you'll see a xp wall (f.e 300k xp for one level, while quests give you around 6-10k)
It doesn't mean the OP is wrong. It still means that there is a problem at lower level. Of course you can also skip a lot of content, but it's hard to do
