:confused: I had 20.04 % on my Exp bar before instance. I won 418...M of XP (lvl 88) after killing the last boss but I have always 20.04 % ! :confused: or I'm wrong??? dreaming may be??? I don't think so !
Try check you distance between you and raid.
If you get "fear" and NPC's kill boss in a long distance from boss to you, you will see message of experience get, but you dont get the experience.
