It is obvious that there is underhand play going on in arena, with people joining groups in Line to notify each other about positions etc. Which I ignored as arena is not worth the time and effort to maintain any decent level of rewards.
But recently we have experienced the same kind of game play in fortress fued, which is unfair and against the spirit of the game, with those few individuals looking to ruin it for the majority. These people create a guild with barely any members so when they are matched up and ready to begin the event, they all of a sudden fill up with top ranked players and dominate against much lower opponents. They obviously can't compete against people of their own level so prevent anyone else getting there.
This kind of thing should be looked into and stopped igg.
