Guild Wars 2

Is it account shared? Meaning if I make a path on one of my characters, do i get reward if i do the same path with another character?

It is bound to account.

E.g

If you ran AC Ex P1 on character A.
Switch to character B and run P1 again you will be hit with DR.

You will not get the full 60 tokens on both characters.

I run CoF on 3 characters, P1+P2.

On first character im sure i gained 60+60

On second it was 30+30 – Which is interesting since, running the same path – normally – rewards you with 20 marks.

On third character it was 60+30.

Honestly i cant see a pattern here.

Hmmm… That’s strange. I assume you know that if you run different paths you are rewarded the full reward.

E.g if you ran P1,2,3 for the FIRST time during the time period
Reward: 3×60 tokens, full 60 tokens for each path.

If the same path is ran twice or more in the same time period you should be hit with DR.
Maybe it still needs sorting out. I have always been hit with DR in the expected manner so can’t comment on that.
