Guild Wars 2

Hi all!
I m rather new to gw2, been trying to level a warior as fast as possible and I ve been doing events (killing champ mobs in queensdale) for awhile. after level 60, every now and then, totally random i get a golden contribution that gives me 300xp. Next time I do it it gives me the full 5k-6k xp. Any ideea why this is happening cause it doesn t make sense to me.
Any help will be highly appreciated, thx.

You’re hitting DR (Diminishing Returns). It occurs when you do too many events in the same area. If you’re hopping between the same 2-3 events that are rather close (say, Troll, Bandit, and Oak), you’ll probably hit DR. Spread out and hit Boar/Wasp more often. If that doesn’t shake it, switch to another zone for a while.

Thank you, will try.
