Detheroc isn't THAT new, it was born the same date as Wildhammer. And for a couple of days a lot of peeps swapped between Detheroc and Wildhammer, and ultimately chose Wildhammer due to less assholes (on alliance side).
During my last guild encounter myself and three now-former guildies were discussing their retarded "we're a family philosophy" and how I need to constantly ask about shit until "I know them better" atop Thorium Point. Well soon enough a Horde shows up, rogue around our level. He talked to NPCs and left, with me constantly keeping an eye on him. About 10 minutes later he returns with two more Horde the same level, a shaman and a warrior. They sit there watching us for two minutes and then after the idiots in the forrmer guild said "Let's go" and proceeded to leave the warrior charges and the melee starts. While we were winning for the first 3 minutes it was a constant graveyard respawn and the Horde were healing/rezing their own. Retarded former guildies decided they weren't going to heal me and I sat dead and watched the melee.
What turned into a small scuffle in Searing Gorge quickly escalated into a near raid as a dozen more Horde poured up the path into Thorium Point. Eventually we were shattered and the Horde began roaming Searing Gorge looking for Alliance to gank, and last I had heard they moved into the Badlands and Loch Modan from there.
That kinda thing happens all the time on Wildhammer. Horde outnumber us 1.2 to 1 and they are more apt to help each other out and heal each other. So much so in STV you never see a horde without a lvl 55 - 60 "babysitter" making sure they don't have a hard time questing.
