Yet another thing you pulled out of your ass. Unless you really believe Varian managed to knock something weighting 20 tons off the airship (or, you know, didn't become a smudge when it hit him earlier). Also, I think @Combatbulter's point was pretty clear in that even if the airships were somehow better, which you based on nothing solid, is not the great military advantage you paint it to be if it can be destroyed by bats.
Their civilization consists on relying on Naaru technology, abandoning pretty much everything Eredar behind them, hating Fel, demons and Warlocks and constantly escaping the Legion. Top notch civilization they established.
Other than them losing territory over the years.
And Draenei and Man'ari are still the same race. Given how long they live, they still remember each other on personal basis. Look at dem strong ties. Or maybe them having common ancestry means nothing. Whoa :O And there was an ongoing rivalry between Stromgarde and Alterac. Which, lo and behold, did include wars. Gilneas was isolationist. Alterac betrayed the Alliance and was destroyed for it. Smaller kingdoms clashed with Lordaeron leadership even after the Alliance is formed. Which is why almost all of them left it after the Second War. And http://wow.gamepedia.com/Gnoll_War is where northern kingdoms refused to aid Stromwind. Oh, well, at least you correctly called your post willfully ignorant.
The message of "greater good" just oozes from this elaboration of yours. Especially the part about Alliance crumbling because Lordaeron didn't agree on genocide.
And Horde's leaders don't count, because reasons.
Jesus Christ, this is just sad. Battle for Gilneas battleground happens after Silverpine questline. In which, you know (OK, that's just a figure of speech, you obviously don't know squat about the topic), 7th Legion was defeated and Worgen capitulated, leading to Forsaken victory. Battle for Gilneas is a new attempt by the Alliance. A failed attempt, since as we can later see in Fangs of the Father questline, Gilneas is controlled by Worgen under the control of Black Dragonflight. Ans even later we learn from UVG that Gilneas has been abandoned.
Icecrown "betrayal" wasn't led by Garrosh, Garrosh disagreed with it and reprimanded the leader responsible and wasn't a betrayal because Alliance already started a war. The bit about Wrathgate and trying to pin it on Sylvanas, as well as putting Putress' name in quotation marks is just dishonest horseshit of the highest magnitude. Andorhal was an attempt to secure an outpost on Undercity's doorstep. Where the civilians officially formed a militia. And then attacked the Forsaken and broke the truce with them that Thassarian made.
Gnomes lost the majority of their race when Gnomeregan fell. Humans are from a kindgom that was demolished by the Orcs. Orcs' population was rather large, which is why it was so costly to keep them alive. Not all were enslaved to begin with. And they didn't lose "large numbers" on the voyage at sea. New Forsaken have free will. Val'kyr's number is irrelevant since they resurrect people en masse. During Cataclysm it was hundreds daily. The original Forsaken amount to half of the Scourge Forces in Lordaeron at the time. Blood Elves are 9% of Elves that survived the Scourge invasion. Kael only took a small force.
That portrayal of Gilneas' situation is bullcrap even when going by what we see in-game.
And then WoD happened where Alliance had losses like an entire expedition led by Taylor or one of their largest outposts on Azeroth while the Horde lost three Shadow Hunters.
First, what was before WoD and Legion. Secondly, that was even before their MoP clarification/retcon that only a minority of Orcs followed Garrosh.
Forsaken still have four Val'kyr. Orcs have Saurfang. Vol'jin was a failure so no leader is better than him.
Which is why Genn attacked the Horde on his own, against Anduin's orders. And since we don't have a compedium on city sized and populations, the claim about Stormwind is unsbustantiated. Stormwind had to be rebuild from ground up after it was decimated by the Old Horde. It doesn't put positive prospects to its size or a population number that would lead to that size.
They always had a limited supply of them.
So you didn't see what Goblin engineers were capable of during MoP?
Garrosh did.
A minority of Orcs followed Garrosh to the end. As for the Alliance... Draenei were hunted by the Legion for eons, were almost wiped out by the Orcs, barely survived fight with Kael's forces and then were invaded by the Legion, with all of their survivors managing to fit under a small dome of light made by Velen. Gnomes blew up a majority of their race. Night Elves imploded the world, banished a large part of their race, lost people in Satyr War and War of the Shifting Hands, sacrificed their immortality in the Third War and then had their ass kicked by the Orcs constantly. Playable humans are survivors of a kingdom that was burned to the ground by the Old Horde. Worgen fit in a tree in Darnassus. The only races that didn't suffer colossal defeats are the Dwarves and the Forsaken.
Yeah, that'd worked wonders with Kor'kron stationed in their capital and Garrosh sending his generals to watch over Sylvanas.
The Worgen were already attacked before Sylvanas got involved. What was she supposed to do? Tell them it was all a prank and hope they give a shit?
Which is seen crystal clear in Legion, where Azeroth is on the brink of annihilation and instead of working with the Horde Genn attacks them. What a total not-idiot you got there. Genn, the diplomat of the year. Hell, he had trouble working with the Alliance at the start.
*Meanwhile in Bilgewater Harbor and Underhold*
That's actually a boon to the Horde.
Well, there's that, but he still wanted to steamroll it before he saw that (and after he was informed by Jaina that the Wrathgate was on the Legion and rebel Apothecaries).
The Alliance wasted a lot of manpower in Cata though. Because Varian was a moron and he thought he could open 50 different frontlines without stretching his forces too thin.
