BST's is absolutely worthless. There is no time I would ever kill a 5 minute recast pet just to get reraise. The only time a BST would need reraise is if he DIDN'T have a pet because the pet is always the center of the enemy's attention.
Take it back and give us what you gave to PUP, or to DRG, hell I'd take what you gave to SMN if the pet tp requirement was also removed for the duration of the ability. Don't give us two worthless two hours.
It doesn't even make sense from a storyline perspective. We don't share any sort of spiritual bond with these pets like a DRG does, so absorbing them seems strange. We just fed them so they followed us home.
