Ya, the beastlord thing really intrigues me. They are super overpowered from what I have read, mostly due to needing to buy an expansion that is $40 per account just to play it, it's an optional expansion that also unlocks mercenaries, but their pets provide group buffs in all forms, offensive / defensive / heals etc. So that combined with a mystic pet is 4 pets on the target. Pretty cool
