I just lost over 22,000 experience from one game. I hit level 50 needing only 3800 experience, but gained 2,800 for winning the game, 1,000 for hitting an assassination commendation, 5,000 for hitting the extermination mastery and 17,343 for hitting the monthly. I thought maybe it would carry over to my first specialization, but it didn't. :(
The only thing that bothers me is that I don't get any of the commendation or challenge xp and all that. Why can't they just let the xp stack like that one time they capped it cause of boosters in reach?
