Did you know that you can check wether a player of the opposing faction is online/offline?
All you have to do it type /invite
If the enemy player is offline, you will get a message saying "Could not find bla bla bla"
But the interesting part is that if he is online, you will get a message saying "Target is unfriendly".
Could be useful for checking wether that annoying elemental plateu ganker is online or not
i dunno if its a :repost: but ill take chance
