Guild Wars 2

So I’m really big into Dynamic Events in the open world. I really enjoy doing Dragons, Catacombs world boss, and temples. Many times I’ve run certain events (such as catacombs) and I notice that by the 2nd time i start getting worse rewards. It is usually rare +greens on first, then i start getting all blues. I’ve run it 5 times in a row and never got items that were as valuable as I did the first run. I notice this with dragons too. If I do dragons all day, I start getting worse and worse rewards. I remember I did dragons every day for an entire week and it got to the point where i was getting blues with an occasional green. Then I took a break for about a week, did it again and I receive a yellow from each dragon, on one dragon I even got 3 yellows…Waited 3 hours and did it again, all blues on every single one. I’ve talked with other players and they notice a similar thing. Im a bit angry if its true because I feel like as a dedicated player, I’m not getting reward as well while the casual occasional player is being rewarded more with the objective of getting him attached to the game.

Does any other major dynamic event runners experience a similar outcome?

For me its a little different. For example, if I run a dragon event first thing sometimes I get blues and greens. Sometimes if I run a dragon event as the last thing I do before logging off I will end up with multiple rares and greens. I have yet to see an advantage of running events like this first or last.
Sometimes I will do all 3 dragons in a day and get rares only from one of them, those can be in any order. Sometimes I will run all 3 and get nothing but blues and greens, sometimes all blues.

The MAW event usually gives me greens or blues. I have yet to get a rare from that.

I think its just all RNG from those chests.
