actually i think maoseitun is right about the war starting in wrath
varian declared war after the battle for undercity
and also as was said there was grizzly hills
and a part of icecrown was a huge battle between ally/horde/scourge forces
Varian declared war, but he didn't actually start it. There wasn't any escalated conflict or anything until Icecrown, which was far from a "huge" battle. It was both the Faction's gunships gunning for the same goal, and cannonically the Alliance won.
That's it. That's the extent of the "war" which Varian declared. I'm reasonably sure that, despite declaring war, Jainna talked him down and he decided it wasn't the best course of action; which is when Garrosh launched his multi-pronged surprise offensive in Shattering.
But hey, if you want to RP as paladins still thinking of mages as soulless monsters go right ahead...
Jesus Bloody Christ, could you straw man any harder?
You're seriously going to try and compare Day of the Dragon, a book which was written nearly 12 years ago as an addon to WC2 and well before WoW came out, to something Metzen said just a couple of years ago?
Good god. Why not just harken back to the days of WC1 where the Humans and Orcs had been fighting for hundreds of years, there was a literal God, and Angels were on the side of humans?
The "thing" here is that this isn't a piece of information which isn't just shown in the Lore, this is straight from Metzen's mouth. He said, fairly recently in the grand scope of things (hell, I think it was near the end of wrath wasn't it?) that he doesn't like halfbreeds. He also went on to say that they are and always will be very rare in wow due to the fact that he doesn't like the idea of a bunch of them running around like you have in most other fantasy universes.
Where as the thing you quoted is not only very old but also something which was stated "in character" in a sense, the comment on Half Breeds is quite recent and stated by what might as well be God himself. If you want to toss it out the window on the grounds of "lol, old" (when 0 to 1 new halfbreeds have been added to the cannon since he even bloody mentioned it), you're going to half to toss out at least 50% of the lore we know right now.
Draenei hate Orcs because of the genocide? Welp, we haven't seen any recent indication of that in the scope of what you consider old, so might as well throw that out the window!
Blood Elves addicted to magic? Pft, we haven't gotten an update on that since well before Metzen made his half breed comment. Hell, we can't even be sure that the sunwell still exists due to the fact that it also hasn't been touched on since then! It's so old it probably just died of old age!
Dwarves and Elves (of all types) dislike eachother to a certain extent due to vastly different cultural ideas as to nature and how ot treat it? Good lord, we haven't gotten word on that since vanilla! IT MUST BE OLD LORE AND NOT EXIST ANYMORE!
Do you see what I'm getting at?
Not only is our source Word of God material and quite recent, but it hasn't shown any indication of being changed or counter-acted on Blizzard's part. They're sticking with it. There for you're grasping at straws due to your inability to ever lose and are attempting to brand it as "old" so you can dismiss it.
The problem with that is, if that's old, then we can toss just about everything we bloody well know about Azeroth and Warcraft out the window on the exact same grounds. This stance that you're taking is literally the gate way to "All lore is old, nothing is known, go ahead and do whatever the hell you want."... Which more or less explains why you actually think it's a viable grounds from which to argue.
I don't need to create an entire speech on how I was wrong,
— used to admit that someone has made a clever or effective point in an argument
You say you like to argue or debate? Well the acknowledgement of superior arguments, good points, solid paths of reasoning, ect ect is one of the basic cornerstones of doing such.
