All, I played halo4 to sr 80. At sr 80 I purposely chose not to choose a new specialization. I then played about 50k xp beyond sr 80.
I wanted to see if the servers would bank all the xp and apply it all at once when I eventually chose a new specialization.
Then I didnt play for almost 2 weeks (work trip). Booted up today and now im 17k into SR 78. Ive essentially lost 2 sr's plus all the points beyond sr 80. How does this happen? Is there somekind of xp reduction for not playing over an extended period that im not aware of?
