There is no reason you cant grind it out while working on a bonus and there is no reason you cant always be working on a bonus. At $25nl about all I did was simply play at party with no bonus except for when they did their reloads. Now that Ive been at 50nl for a bit Ive decided to start doing a lot more bonuses. check out www.bonuswhores.com and find some good ones and work on those while playing your regular game .
