Today i did duty finder frontline with my reaper (level 72).

I got 1,3 mil normal and 1,3 bonus and like 300 k for frontline itself.
I started with level 72 with 1mil exp from the 3 mil needed to level up and i ended with level 72 with 2.6 mill from the 3 mill needed. Despite seeing in the chat i got almost 3 mil exp i really ended with 1.6. So for some reason i didnt get the bonus exp? I was my first frontline of the day so ibwas eglible for the rewards.

Anyone can help with why i got less exp?
