Guild Wars 2

Hey guys, my issue is this.

I have 5 level 80s.

At times, I would do AC paths 1-3 back to back in less than 90 minutes,
Swap to my alt level 80, and do it again and still get 60 Tears per completion. with no break in between.

However, Earlier this morning I completed AC path 2 twice back to back…
collected 60 tears, swapped
to another 80 and did AC path 2 again and only received 30 tears.

How are completion rewards handled ?

Does each individual character get a separate dungeon reset timer (Meaning my 5 lvl 80s can bag 900 tokens a day for the same dungeon)?

Or is the dungeon timers all based on the account?

You can get hit by diminishing returns a few different ways. Completing too many paths too quickly will lower your rewards. Also, repeating the same path will lower the rewards. Sometimes doing either of these with other characters on your account will not run into DR, others it will. And occasionally you will just start out nerfed, having not even been logged in yet that day. Basically, the anti-farming system is still in need of serious adjustment (or at least have an Anet employee specifically state the criteria).

Shortly, DR affect the account, not the character.

If only it were that simple. There have been many times where I could do the same dungeon path on other characters and been fine.
