If you at least take time to read this post and attempt it, it's currently possible to get up to sevenWintergrasp Marks in a single Battle.
This exploit only works if your faction is on offense.
On with the post:
In this post, I'll be covering a way to finally use that pesky lag that you get every time you win Wintergrasp.
Now, as I said, you need to make sure that you do win Wintergrasp and of course be in the match when it happens.
First: You should probably join a raid group so that you can get credit for your dailies (If not done) faster, plus get honor for any [Insert opposing faction] player killed that was nearby.
Second: When the Battle for Wintergrasp begins, take the portal from Dalaran into Wintergrasp and play the match out in whichever strategy it takes for you and your faction to win.
Third: Now that your team is about to win, you have to try to get your raid to time it just so perfectly that you win exactly when the game ends.
Result: 3 Marks of Wintergrasp for winning, 1 Mark of Wintergrasp for losing, and 3 Mark of Wintergrasp for Defending.
Before you flame, yes, I realize theres barely more than no chance of you being able to time this right, but it has happened before, and if you pull it off, gratz. If you don't, I apologize.
- I also realize there's the risk of losing and only getting your one mark for doing so, but in exploits, aren't you always risking something? Exodus proved that to us recently.
