Guild Wars 2

I have a question about diminishing returns with regards to loot. If I farm CoF, for example, and after 5 or 6 runs I’m experiencing DR, then switch to another dungeon, will I see DR on loot in the other dungeon (say, TA)?

you get DR in rewards from completing CoF (I’m not talking about loot, I’m talking at the end of the dungeon, where you get tokens, gold, exp). doing another dungeon will not by itself remove this DR, but the other dungeon may take long enough to remove the DR by simple time waited. going and watching a movie would do the same thing.
DR of dungeon rewards is on all dungeons over a period of time. It doesn’t matter which you do or which path, if you complete 3 inside a a short period of time (I think it’s an hour), the 3rd will have DR.

is there DR of loot though? or is it just tokens?

I never hear much talk about DR on the loot from dungeons, mainly just DR on the dungeon rewards.

Then again, I never hear much conversation about the great loot from dungeons, just dungeon rewards!

If you are hitting some sort of DR from a particular dungeon, switching dungeons SHOULD solve your issue. The mobs are classified differently and that is usually where the problem lies.

Is there a DR on chests in dungeons? does that count as loot?

When I run multiple CoF P1’s, I notice that the first few runs seem to have decent loot from the chests (molton cores, yellows, etc.) but by the 3rd or 4th run, it’s all blue and maybe greens in the chests.

Any confirmation on this?
