Guild Wars 2

I did the dungeon for the first time today and I only got 30 charr carvings, on multiple characters? whats going on with the rewards for this? did it get changed?

On my warrior I only seem to get 30 tokens as well on the first run of the day, then 20, 10, etc

Whereas my Elementalist and Guardian will still get the 60 on first run, then 20, 10 etc

Something is wrong with this.

30 tokens is DR reward. You grind the same path across characters, one after the other, and this is what you get.
