So lets say you have a friend with you and your team on Skype. He is not playing in your game, just spectating......Need I say more?

Is this something that happens a lot? Has this been addressed before?

There is a 3 minute delay, so him telling you there is a guy in the bush next to you.. That info would've maybe been useful aboue 2 minutes and 30 seconds ago.

They only thing they will benefit from this are buff timers and dragon and baron timers.

And if they are serious about using this as a cheating tool they may find ward patterns and pass that info on. since most people only ward a few places over and over.
