Yesterday I went to TA EXP2 FOR THE FIRST TIME and get only 6s. Later on I went to CoF EXP2 and get less, 3s only.
Both of them are my first time running that day(I get 15 tokens at the end.)
Today I went to CoE EXP1 and get 13s(that is my first time playing this route. I get achievement and 15 tokens at the end.)
And one more thing, I play with my friends on these 3 dungeons and they all get full 26s at the end.
