ok let me explain.. IT IS NOT client sided NOR PATCHED (stupid nexon) but listen..
You DONT loose exp. once you get into the noob channel you must UNFREEZE your exp (or it will crash). So,
once inside the channel your exp will be back to normal then you go play a game and you get exp normally except that you get more kills cause you play noobs who don't know how to aim right yet
-edit-
ive gotten 2 levels in like 1 hour 30 mins cause i wreck noobs hahah its sad but funny and fun
