The problem with the quote is Blizz has spent years weakening the Night Elves to the point they dont resemble anything from Warcraft 3.
The Zandalari were not dominated by Sentinels which did not exist at the time. They were dominated by superior magic of the Well of Eternity in the hands of the Night Elves. Also men used to dominate the Night Elf army until the Legion basically destroyed it during the War of the Ancients.
Not to mention the Zandalari and all Troll Empires were nearly destroyed by the Aquir and were a shadow of their former selves. If not for that even the Night Elves superior magic would not have been enough to defeat the Zandalari and other Troll Empires.
