I would be really interested in writing this. I have played both Alliance and Horde but only Horde in the last 2 and a half expansions.

Those points that were brought up were good, there's a few more that the Alliance did towards the Horde, except that no one considers these 'Horde' since it's not a 'city/village/town/camp' that people could get to with NPCs for players to interact with.
You've got the Shatterspear Vale situation. The dancing trolls of Vanilla. They may have made an offensive towards the Night Elves but the Night Elves went in there and stomped the ever living crap out of them.

You've got the Siege of Splintertree Post. That would have been a win to the Alliance if the siege hadn't gotten broken. We have to fight our way in there and then we're really really hurting there.
Plus of course, the whole crappy situation in Stonetalon Mountains. (Killing innocent baby druids does not sit well with me.)
Now, as for Gilneas, at the end of our quest chain through Silverpine Forest, we lose Gilneas right back to the Alliance. Or at least the Worgen. Crowley (from the Worgen starting area) leaves back to Gilneas after pushing the Forsaken offensive back to the great gate there.
But that's a couple more. Anuillae, if you'd be interested, I'd love to do a tandem post with you!!
