"...it wasn't that incredibly difficult: it took at most two or three tries in each battleground for each part of the achievement. ...you'll often get an attitude of fellowship from everyone since everyone's trying to do the same thing..."

At most two or three tries in each battleground? Attitude of fellowship? I'd like to know what bgs YOU were in! Sure you didn't stumble into a premade made specifically FOR the achievement? The only fellowship I've seen in non-premades was from the 'enemy' team. On that note: there is a reason that I keep Hallow's End costume wands and the Noblegarden bunny branches in my inventory on every toon I plan to try SoHK on. It's so I can CC the same-team griefer who's trying to annihilate the 'enemy' player who came across the battleground to help us with the achievements. (You can't attack as a bunny or wisp.) I also take it you've never run into the people who make it their mission to ensure that no one in 'their' bg gets any part of the achievement done. I've seen paladins bubble flag-runners. I've seen hunters switch on Aspect of the Pack so that a flag-runner would be constantly dazed while trying to run. You can completely forget about anyone wanting to heal you.
