hmm just do one man army match.. 16 players.. match would end every 3 minutes.. u get 300 -500 exp depending on how good u do. and another 3 min and another 3 min..
u could be in 3 matches under 16 minutes in one man army and with a total exp of 900 or more depending on how good u do..
much better than sitting for 16 min just for 500 exp...
