Understanding how EXP is gained:
EXP point gain is determined by:
1)Length of game.
2)Number of players in game.
3)Whether victory is achieved.
GARENA AFK EXP MAP GAIN TABLES:
(basic member)
For each additional player in AFK map you gain an additional 40 EXP points.
E.G - If there are 10 players in you game you gain 400EXP points per hour.
After 10 hours you gain 4000EXP points.
EXP Formula -  (40a)(b) + (20)(b) = c       where, a = number of players ; b = number of hours and c = total EXP gain
20 refers to EXP gain for simply being in channel.
worked example - (40x10)(10)+20(10)=4200
                                 
4200 is TOTAL EXP GAIN AFTER 10 HOURS with 10 PLAYERS
FOR GOLD MEMBERS THIS IS DOUBLE! (8400EXP)
