Any time I play Castle Wars with friends we gang up on the people stealing our flag, and ancient the living daylights out of him. Then of course one of us gets the flag. There's nothing wrong with it, it's how you play, and how you win. And honestly, most of the time it's a level 20-40(though I have killed 100+'s for the flag) who thinks they are awesome and gets the flag, then loses it and gives the other team the flag. Maybe if we had a certain level barrier or something so you had to be like 50+ to play then the game would be fair.
