You get a certain amount of exp every match when you win. If you lose a match, depending on how bad you lost, you lose a certain amount of exp.
Say for example you have 100 exp. You win a match and get 1 more exp. Then another with another win. Then lets say you come in deaad last on the losing team with like 5 kills. Your experience could go down by like 13.

you never lose experience....only if u leave a game..

and it did this because u have to face people higher lvl than u to lvl up and have a positive kill/death ratio...and if u lose to someone lower lvl than u r than u will lose a lvl..
thats typically how it works..

or if u did horrible in a match than ull lose a lvl as well like if ur kill/death ratio wasnt positive...hope this helps
