Ignoring all the vitriolic night elf related arguments above, and getting back on topic
If all the races were separate and working independently in the state they are now and not part of larger alliances and factions, the Dwarves would easily be the strongest individual playable race.
Unlike almost every single other race/group that makes up the playable races. The Bronzbeard dwarves never suffered any catastrophic losses of life or defeats.
The kingdom Stormwind was razed to the ground and for a timer its citizens were refugees
The Night elves just suffered a geneocide that bite them to the very marrow
The blood/void elves are the small surviving percentage of an older geneocide
The Tauren were nearly wiped out by centaurs
The Darkspear (an already tiny tribe)had their island invaded by naga, most killed, survivors then fled, then had half their people turned into voodoo zombie slaves and then got attacked by naga again.
The Orcs were the remnants of the old horde that escaped internment camps and fled across the ocean. And due to quick aging and brreding they may have bounced back, they’ll never be as strong or numerous as the old original horde
Draenei…do I even need to explain? LIke almost their entire planet joined the denons. Only one space ship of people became draenei and a smaller fraction of that, Lightforged. And then you taek their further genocide of their people on Draenor. And even more were pro0bbaly lost in the Exodars crash
Gnomes lost their city due to bio-nukes and radiation and lost a large portion of their population.
Gilneas - again speaks for itself. Civil war, fol;lowed by mass worgen invasion then further survivors were invaded by forsaken.
Bilgewater - Made up of the surviving members of a single city on Kezan, who then became slaves on an island.
Zandalari trolls- Their empire is practically crumbling apart at the seams and barley control even 1/3 of their own island
Highmountain - These guys arent as hard off as the rest. Assuming the tribes are about equal size. About 1/4 of their population joined the legion. Though their population was never huge to begin with. The drogbar tribe though has mostly made up for the Bloodtotem loss
Nightborne - City sealed away for 10k years, many of its citizens exiled to face death, legion comes in, large portion start drinking fel juisce and fight for Ellisande.
Forsaken- Might not be as worse off as suome considering their population does not require things like food. But at the same time, they cant reproduce and the only way to gain more is if a val’kyr is nearby, which Sylvanas has precious few of left. Also they just had their city nuked and most of their forces driven from the eastern Kingdoms. The forsaken army alone isnt as great as people make it out to be, remember in Cata the entire forsaken war machine was ground to a halt and then started getting driven back by Gilnean rebels and the 7th legion.
But the Bronzbeards came out on top above everyone. During the Second war, as soon as the orcs starting invading Khaz Modan, the Dwarves just all held up inside Ironforge and waited it out, all safe inside. Ontop of that they have arguably the most reliable and easily mass produced technology, the single strongest most defensible city on Azeroth. And since Cata their numbers have swelled, being bolstered by the inclusion of the Wildhammers.
As a race, the dwarves as a combined Kingdom, now hold the most territory and land over every other race. Dun Morogh, Loch Modan, The Searing gorge, Blackrock mountains, part of the Burning steppes, the northern half of the Badlands, the Wetlands, good portion of the Twilight Highlands, Sections of Alterac and about half of the hinterlands are all dwarf territory.
Call me biased if you will, and apologies for a giant wall of text for pretty much nothing…but ya
