Well like so many people like to talk about numbers, there’s not as many of us as there are Night Elves well… were there’s less now I guess 
But for being so established and ancient being tricked and outsmarted with all the resources of the Night Elves does seem to speak volumes on your own races failures imo, Malfurioun being shocked they scaled Felwood, like really? My man really left part of the forest unchecked and was like but how are they coming from the north AWE YES FELWOOD
ALSO the scale of your failure vs the scale of our failure isn’t really comparable shrugs
