100% sure they were not leashed on classic. The thing I don't recall is them flurrying or being so beefy. I remember 13 years ago killing vulak and then we would celebratory rush the pets in his lair because they were easy and dropped good loot like monk/rog necks.
Picture of us in Ring of Valor on Bristlebane killing vulak then going to his pets in lair, as you can see Keys lands a tap on Dktan'Nirsl one of vulaks guards.
