Mate.. dont worry. Just play... forget the rating atm and learn, get exparions, get gear, and in some time you will start slowly wining your way back up.

Also, its the first week of the new seasson, i hit 70 a munth back.. i got some nice gear now. but i did better back a few weeks ago with alot worser gear then now.. Its all becouse the good teams are rating back up and most of them are still in the 1500ish now as most start with 2v2 and 3v3 first.. So dont worry. next week most of the better teams will be gone and we will do better
