I am a level 16. My experience points received for normal kills (32xxx XP) without the witches whistle is 71XP. With the witches whistle it is 128 when it should be 142 (71+71). I am using an add on that shows experience received. I also suspect this carries over to other rewards as well.
Could the raise in the champion cap have caused this?
Curious if anyone else noticed this.
