You want to know why why she gives out only hunter bounties is because one 31 warlock with a 21 hunter complained about the first 2 days it being only titans that post got 20-39 replies with all of them knowing that there would be warlock and hunter bounties
So next day they decide to pretty much always make exclusive bounties to hunters I mean it's not -blam!-ing rocket science just make a bounty for each class everyday you fed up to the b8 of some warlock like really could I have joined your company at the age of 2?
