Guild Wars 2

This would be an anti cheating option since we can spectate other players and see if they teleport or use speed hacks.

If you have been killed by someone, make the name appear on the chat log. For example:
You have been killed by XXXXXX.

Also include a console command to spectate the player just in case it is a thief and you cannot click on the player tag. Example: /spec XXXXXX

I hope this gets in the near future. This is a great way to create an anti cheat police.

Thank you.

you may have just suggested the greatest spy machine gw2 could ever have

This wont happen due to the fact it would make spies even easier.
