Guild Wars 2

I got 7-13k xp from events and then after playing for over 1 hour i started getting like 648 XP. What the kitten?
This is from farming labyrinth.

Also the legendary events give too little XP for the amount of time it takes to kill the legendary. Got same amount of XP that you get from the veteran event.

This is a mechanism to prevent farming, working as intended.

Do some other stuff to gain your xp then.

No i think it’s a bug. Farming in GW2 is legal.
