I got the new class with Legion Tokens. It took one day farming the Exalted Champion quest.
I don't think that the Blademaster is strong, but it's AC, will be rare and it's from Dage.
About the new Paragon Pet, the quests sucks, both of them. I was thinking to buy it only because I don't have any Paragon pet, but the prince is high.
I could buy the entire Love Paragon set with 2000 acs.
