Just doing the math they advetise publicly (as a recruitment for pumpers and buyers i guess) if they are making 250k+ pots in MC/Bwl, 250k+ Aq 40 pots, and 600k+ (most items presold anyways pots) and they do all raids 3 times a week each… their whole Gdkp group is bringing in an estimated 3,300,000 in hold per week on Era.
The leader gets 10% per raid so thats 330,000 gold alone he gets just for him to do whatever he does, not to mention his cur of the raid pot.
