Doubling

"Doubling" is the term used to describe a player who is attacked by two enemies at the same time. For example, your ally could have fallen and it's just you versus two of your enemies. They're both allies. They both attack you from different sides simultaneously making it extremely hard to fight off and recover from.

Is Doubling Frowned Upon?

It depends. It varies from player to player. Many think that doubling is favoured by noobs. Some see doubling as a quick way of finishing off the enemy and ending the game. However, if two players are to double an opponent they are expected to do it fairly and not to antagnonise their target by gloating or insulting them.
