When farming, only attack 2-3x, regen, and repeat... U get more $$ that way... Also earning depends on stats, and $$ the player has out.(it's best to fight a little bigger than u)
my personal farm faves are the ones with unbalanced stats...
Examples:
•34020/5656
•blueshift 6734/40500
(both inactive)
Of u are stronger, I recommend
•getoveryourself 64794/24960(4pots)
