None of those points require you to have more than one job boosted. Would you look at that, all the talk about playing with friends and reaching end game faster was bull. In reality people just wanted to throw money at the game so they don't have to
actually complete the things they want completed. You'll probably get what you want because nothing persuades the devs faster than a horde of people trying to lose their money. I just hope they keep crafting and gathering out of it so that the boost potions don't screw up the markets for everyone.
