Can someone explain it

play game...

Same way... I just took a lvl 35 too 74 in a out 2-3 hours

Campaign -capstone2-capstone3-tree whispers

Can you explain the way since you can't enter wt3 or 4 without meeting the level req

If you decide to skip compagne?

They fixed this in the patch just before launch.. No longer has a level requirement

Is powerleveling again available and how? Dungeons?

You can power level.. But you will have reduced experience after the patch. And same method as before, yes. Nightmare Dungeons is going to be the go to! I’d expect services to be coming available very soon! They might be a bit expensive though.. especially considering how much slower you will level
